First of all, we have no control on the game client itself... The programmer has stopped working on the game a while ago and has not shared the source code, so we can't fix it, sadly. The problem is caused because the client uses some kind of ... unpacker that uncompresses the executable before running it. This makes the game harder to reverse-engineer and adds some level of hack-protection. However, this kind of unpacker is seen as a threat to some anti-virus programs. On top of that, Continuum has some anti-hack features that make it hard to access or modify the program's memory and stuff like that. So the anti-virus tries to kill it, or it just scans it and it kills itself... It causes all sorts of problems. Anyway, that's why I understand it can be so capricious, I could be wrong on the details, but you get the general idea... Yes it sucks.
