Hello everyone! I'm brand new here and just started playing Baldur's Gate for the first time a couple weeks ago. I'm having a total blast. However, as the thread title implies, I'm having a problem. I know that I caused this. I installed BGtutu with SotC, then deleted the original BG and BG2 files and had no problems doing so. Then I wanted to change the portraits and appearances for some of the party members so I installed Shadow Keeper (that's all I used it for, I swear) and had no problems... up to a point.
When I started to change the skin and hair color for some of the characters, that particular save game wouldn't load, but the unchanged save files would. I kept changing things and experimenting to see what would let me load and what wouldn't. At one point, when I tried to load entire screen flashed blue with some white text and then my computer restarted.
I'm not very computer literate, but that didn't seem like a good thing.

Now I've gotten it to a place where I can play the game, but sometimes when I save it does the blue screen flashy reboot thing. Do you think I'm causing damage to my computer (XP btw)? Should I stop being so picky and just try to restore my appearance settings and uninstall Shadow Keeper?
Thank you for any help.
