Not dumb, just new. You'll see some of the "pros" here frown upon people coming in and looking for instant answers, and taking the easy way. These guys put in probably more hours here, than they do at work.
Reinstall then copy the the whole folder. Keep one as your "master" copy, and the other one you can mod. That way you have a file to copy and replace items when need be.
I spent honestly a good two weeks trying to find stuff where I was trying to get a roster for original xbox going again. I saw the light, and found a copy on pc.
The first and most important thing you'll find with anything here, is keep an untouched copy on file, and save your work.
Hope ya get things straightened out
