That would prob explain why it's erroring out. If I knew anything about lua, I'd give you a hand on the GUI. I'll look though some of the ACE/Rock libs and see if I can make a gui. At least we can get the backend working till then.
TBH, I think it should just forgo all GUI work and just have it output to console till we know it works well.
We'll see what happens tonight when we login to our new raid timers. Also, we ran a ZG so that timer will also be in our database. Servers are down and I'm at work so I can't see if it corrected itself for the raid resets.
