Been having the same problem. I install the game, play awhile, try to load it again the next day and nothing. It gives me the white bar under the name of the game in the start menu like the other person got. If you wait long enough, it just deletes the whole folder that the game is in. When I'm able to get to the files before loading a 2nd time, I get messages that I don't have permission to access some of the files. If I am able to open the properties of a file, it won't let me change any permissions either.
When I run it the second time and get that white bar under the name, I try going to task manager to end the process, but the game cannot be found. The only thing I can do is reboot the PC, and when I do this, the game deletes itself and that whole folder. A friend of mine plays it wants me to play. He's had no problem with it, but I see here that I am far from alone in this. It's very frustrating.
I heard there was going to be a patch on the 11th, but from what I'm reading, it doesn't sound like there is a patch, or it doesn't work if there is. Right now, I'm waiting the long wait for the update to download and will see what happens this time. This is my first time trying in awhile to install it.
