I actually enjoyed the XBox version more than the PC version (having gotten the PC version first and played it on and off for several months immediately after release, dealing with random crashes, then installing a 4 gb patch to fix them, then dealing with the patches requiring installing new 4 gb patches, then having it become unplayable due to new patches, and patches making the 4gb patch unusable for several weeks until a new one was released, and eventually they released one which included its own, but by then I had quit playing)
Later I got the XBox version and hey - no crashes, no issues at all, worked perfectly. And it's not like I found any good mods for the PC version anyways. The only issue is that it actually has loading screens.
"The troubleshoot thing?" Not sure how that would be useful. They probably mean having steam verify the integrity of the game's cache? But if you just reinstalled it I'm not sure why it would be bad. It can't hurt to try, though. You have to go to the game library, right click the game, hit properties, go to the 'local files' tab, and hit verify integrity of game cache. (They could mean something else, who knows.)
(I haven't had any issues with the latest patch, but then I was playing it on the XBox)
