Same problem, XP SP3, the bot and client cant run at the same moment
system specs are:
Intel Core 2 Duo E6600
Radeon HD4870 512MB GDDR5
Corsair 3GB DDR2 (Dual Chann 1GBx2 512MBx2)
Asus P5B Basic
If this might help anyhow. When I load the bot first and the client after, my screen goes black and shows signs of major mem leaks (in the way that it doesnt respond to any termination command). The other way around the client just exits with the usual windows error report.
Good luck with the development!
