hi guys,
ive the same problem but also for multiplayer... my version is the official installer, no cheats or hacks or whatever in use... everytime i try to connect to a server it shows me this error message above that Nequinox posted... i can click ok, and it pops up again, and again... the game is in a dead state alltho i can still here the sound... i can only terminate the game with the task manager.... i run xp now... i had 98 before and had crashes with the game on regular basis, but not like this.
one server is an exception tho. If i logon to the "FA Decaying Zombie" i dont get this error instantly, but when i try to post a message it appears. If i click the ok button repeatedly like 30 times it disappears eventually and i could write some text and continue playing after that.
But even when i dont try to write any text the server kicks me when map changes, but not with this error, as i recall, but with a battle-eye thing, that kicks me for some bad package or something. Im banned then for no good reason.
Ive tried a couple of things, like stuff i read in the FAQ, but nothing seems to make the game run any better. I like the game, but until this problem is fixed i cant play it.
Edit: hurray! ive found a solution to the problem, some guy posted on the german "selfkill"- soldat page. You have to right click on soldat icon -> properties ->compatibility ...change the mode to windows 98/me and it will run.
