i just bought the game for pc and as im playing everything is going fine then randomly the game will close is this my computer being stupid or is it just a glitch in the game im starting to get angry cause i lose my progress and its getting unplayable

I'd suggest reading a bit in the hardware section and posting a bit more infor about your computer if you don't find your answer?

Without a lot of additional detail, anybody's answer is just a wild guess. Here's mine:

Either your GPU or your CPU overheated. (You'd probably only see this after playing for a while.)

You can download a temperature monitoring app like http://www.almico.com/speedfan.php

Also, as rumblyguts suggested, try first reading/searching, then posting (with more detail) in the support or hardware forums.
