YARRR SUBY MONSTER!!
For the most part I'm the "fix it" kind of person. Except for windows... If it won't boot I try a few basic things and then just give up. I really hate dealing with windows.... unfortunately most people use it and I end up dealing with it on a daily basis...XBMC is a program, above I noted that it works on all platforms. Windows, Mac, and linux. Just download the program, slap on a good skin, point it at your media, and have fun.
As for your problem, I'd just say screw it and reformat. Windows likes reformats every once and a while, and the time you invest trying to solve your problem vs the time you invest reformating it may make more sense. Then again I suggest reformatting far to often so do as you wish.
