Q Light Controller+

Hello,

I wanted to share a problem I was having tonight. I've been composing a nice little Halloween Holiday show using QLC+ 4.8.1 on a Windows 7 64 bit machine. I've have great success. Tonight, I added another video function to my show. Everything was working ok up to that point. I had four previous video button/functions on my Virtual Console. I had to reset the computer and I'm not sure if I messed up and didn't properly close out of QLC+ or have otherwise caused the workspace file to be corrupted.

I thought it might be a bad reference to the AVI file, so I manually tried to delete any references/functions/buttons related to the last video I added. That didn't help. QCL+ still crashes when I try to load the workspace.

This is the crash screen:

I just feel like I goofed somehow. Only thing I can think of is that I did go back and change the file in the scene editor /video function to a different video. However, I've done that prior with no problem. I am happy that I made a recent backup, as I usually do, of the workspace file. I really only had a loss of a few buttons and restoring my show back to where I left off tonight took a minute. I'm just concerned with this event and wondering what part I had, if any, in causing this.

Hope it was noteworthy. I'm not much of a computer wiz. Hopefully, I've given enough information for it to be useful. I can upload the corrupt workspace file to anyone who might be able to assist. Maybe, it's just something obvious.

Thanks for any assistance that might be offered.

Hi, if you post your qxw file, I may try to fix it and/or fix QLC+.

Hello, I've attached the qxw file. Thanks for looking at this. I'm really more so interested to know if it was me who caused this, or a QLC+ issue. I'm leaning towards something I've done.

Keep me posted. Thanks so very much for the help.

I can open it on Linux.
Maybe I need to try on Windows as well ?

Is it correct that you have only Scenes and Sequences in it ?

Hi Massimo, The workspace has aprox 61 channels assigned to 61 'fixtures' as such. (all generic) There are dozens of scenes and sequences and a Virtual Console. No shows. I'm running is on windows 7 64 bit. Please don't worry too much about the file though, unless it proves helpful to the community and points to a possible bug. I've had no further issues after restoring from a backup file.

Thanks,

Hello, Sadly, I am having more issues with a qxw file not loading. Worse, I'm losing confidence. As prior, I'm using 4.8.1. Please help me if you can. Here is the file.
It's won't load. It just freezes the software dead in it's tracks. I pulled the backup file, loaded that, and it works fine. THANK GOD I'm making backups of everything. This is twice I would have lost my show. If this is related to my system, rather than an obvious bug, let me know. I would like to mention again, that I am using E1.31. I say this, as I wonder if the E1.31 address changing from time to time causes the crashes? (be kind, I'm not a programmer or a tech person, so this might be a stupid comment, but who knows)....

PS: I can't post the error screen, as I am running a Halloween Show in the evenings and don't want to disappoint those who come by to see the show. Tomorrow, I'll post a crash report.

Thanks,

Hi Grumpka, you definitely spotted a bug and it's indeed related to the E1.31 plugin.
It seems the project tries to ouput on a non existant interface.
Resetting the IO mapping let QLC+ to open the project.
Attached.

In case it happens again (and until a bugfix is found), to reset the IO mapping you need to open the project and write this between the initial tags:

Thank you so much Massimo. I suspect the cause was on part, as I was having IP address issues with the E1.31 bridge. I'm working on that now so the STATIC IP will stay just that, static. This certainly explains what happened. I'm relieved though. I can be more vigilant about IP's for the E1.31.

Thanks for the fix. I'll keep this info on hand. And thanks for fixing that qxw file. Much appreciated.

Kind Regards,

Grumpka
