2 days ago, my game (version 2.1) crashed (I was playing the last mission as Sandor), and it didn't just crash, it caused a blue screen! Subsequent attempts to launch the game were unsuccessful - Uplay couldn't synchronize the save files with the service, and the game wouldn't load. At the same time, the computer was extremely slow and kept freezing. The Task Manager showed normal CPU and memory usage - 20% and 40% respectively. A complete reinstallation of the game and Uplay helped.
