Logged in to see what my version of the game was (it was 0.59 stable). Today the game updated to 0.59 stable and steam had already downloaded it, so that was all I wanted to check, so I hit exit and the game crashed with the following Error:

The instruction at 0x00000000 referenced memory at 0x00000000. The memory could not be written.

Click on OK to terminate the program.
