Every time I get to specific places in the game, it locks up in the middle of whatever sound it was making at the time and the only way to get out of it is to force quit crossover. The other thing that happens is that Steam suddenly stops working. I have had to reinstall it a couple of times but the only way the install has been a success is by removing references to the previous install. Unfortunately, this has had the side effect of removing my save games and I have found myself having to once again start a new game. This seems to be happening more with 6.2 than it did with 6.1. Any suggestions for what to do next time this happens would be appreciated.
