Crash when starting second match!?

[Firerain9X]

When I started playing Combat Arms yesterday, I had no problems. However, after 3-4 hours of playtime the game crashes when I try to enter a room a second time and join the match. Every time this happens this message pops up:

"The instruction at 0x6a79be8e referenced memory at 0x00000079. The memory could not be written.

Click on OK to terminate the program."

Is there anyway to fix this (i.e. uninstall then reinstall) or do I have to wait till the next patch comes out?
