i've got a rare bug. Something can hel me whit this bug??? when the game crashes apear this screen

Rebooted yet? I doubt it's a bug.

yes, it's crash a lot of times and some times the PC make a upset of memory.

How much RAM do you have?

You need to click that blue text a couple of times until it tells you the memory address of the crash, and report exactly which version you are using.

You have found a crash. It could be a bug in LFS or possibly a problem with your graphics drivers or your computer.

Whatever the problem is, we can't help yet. But if you tell us the crash address and which version of LFS you are using, it's possible we may be able to help.

i got that bug twice after being kicked from demo servers. hasn't happended to me in S2 though
