Same for me. Game isn't playable anymore, 'cause it's freezing all the time after only a few seconds. Mission is Razor Two, 3 evidences found, waiting for catching Bardak. Patch 1.05 is installed. All the tips 'n tricks I read through the internet in variuos boards didn't help. Game just freezes and has to be killed with the taskmanager.
