This sounds exactly like the problem I'm having. I submitted all of the necessary files to Bioware Customer Service to no avail. I can't count the number of Warzones I've been booted from because ToR crashes. I hope your right about tomorrow's maintenance.

I am experiencing constant game crashing. My ToR client crashes more than 10 times per day. I submitted a ticket about it and was told to basically deal with it. When I responded to that, they referred me here. Does anyone know why this is happening, or when we can expect a fix? At this point, the game has become almost unplayable at times.
