Hi, I've downloaded 1.01 and everything went fine until I started to play training mission. I can usually play game fine some minutes but then the game seems to freeze randomly and after a few seconds I just get a message saying "program has performed an illegal operation" and desktop. - TDM 1.00 has worked fine, I've played every fanmission there is for TDM and never had a single crash with it(including the training mission) - Download operation for 1.01 went fine, all files passed the integrity check - I deleted all old saves before updating, so the problem should not be related to the savegame-files. Though it has to be mentioned that sometimes game crashes just when quicksaving, and then the quicksave-file becomes unusable - I checked TDM FAQ but didn't find any solution from there - One example of crash is when played training mission and from the door that takes you to the sneaking practice. When i entered a place where the first hammerite is sitting the game did freeze. I then started the mission again but the game didn't freeze in that same place and I was able to play the sneaking-part without freezes. Another example of crash was in the room where you have to lit up the torches. - I downloaded training mission again to make sure it's not broken, but didn't help My system is Intel Core duo 3.0Ghz, 4GB ram, NVIDIA 8800GTS 640MT, Win XP SP2 Only thing that comes to my mind is that I've updated display drivers recently(196.21), however all the other games works fine with them. I also have NHancer installed, but right now I'm using just driver defaults. Has anyone else using NVIDIA and 196.21 drivers experienced this? Does TDM create any kind of crashlog that could give some more information about the problem? EDIT: I just played thru "Living Expenses" and "Outpost" and din't get any lock-ups
