Hey y'all!

I bought Skyrim around the release date on steam, and I played it for about two months, till December. I had no trouble playing it at first, except a few color-bugs at the beginning, but that was fixed in a patch. Now I haven't played it for a little more than six months, and I figured I'd try it out again. But that wouldn't happen.

The first thing I saw was that at the main menu, the color on the logo to the left of the menu options had changed. It was now pure sapphire-blue, or something. I thought that it wouldn't be a problem, but I was wrong

The second problem was that I could not load a save. The game seems to be running, but it will not move on from the loading screen, its just stuck.

The third problem was that I could not start a new game. The same thing happens here as it happened in the second problem.

As a solution I tried to check the integrity of the game-buffer. That didn't work.
I also tried to defragment the buffer-files, but that didn't help either.
Neither did it help to uninstall the game and re-install it.

I have no clue as to how I can solve this problem, can you help me out?
