First point, upload did not work, while I was using the dmp files, so I dumped the files together into the zip. file.
Second the crashes occured mostly on two occassions, one is the map Pavlows House, the game crashes there always, not always on start up, but after two minutes max, the game crashes with "ROGame.exe has stopped working".
The other is, when a map change occurres on the server, there the crash happens regulary, but not always, message same as above.
Then there is a third instance, where the game crashes, but this seems to be random, sometimes in the starting screen of the game, or while running around on a map. This doesn't happen that often, but it is annoying.
