QLC failure on DMX output

Hello again.
I've a huge problem with QLC+.
I am running it on a Windows7 PC, I am using a KMTronic USB>DMX512 controller to control a fire projector (simple 2 channel fixture).
I have configured all, I go on Operate Mode, and when i push on the virtual button to activate the projector it works only for the first 3/4 clicks, then it stops working.
If I go to the input/output panel and I refresh the DMX USB device, The projectors works again for another 3/4 clicks, then they stops.
I'have install the FTDI drivers for KMTronic, and they should be ok... I suppose....
I had the same problem running QLC on a Mac using the same devices...
Please, help, I have a show in a few days and I am in a a sea of problems.....

Hello snowblind,

Have you eliminated all possibile hardware sources of error? I've experienced quite some DMX bus lockups due to a noisy environment. Is the fire projector your only fixture on the DMX bus?

Checklist
-Use shielded DMX cables
-Terminate the DMX bus
-Don't run DMX cables close to power lines
-Lower frame rate when you have cheap hardware (a lot of cheap hardware have bad DMX hardware implementations)

Regards Teackele
