Theme Icons Missing

So a while ago, I installed a theme. It was some Alienware theme, some friend had recommended it. After a few days, I got bored of it and reverted my theme back to the default Windows Vista thingie. It was later I discovered it hadn't fully gone back to normal. Some folders icons were displayed as the Alienware ones. Not all, but only some. And they were all in the same area, my Documents folder, strangely. Anyways, I left it at that and since then it has really been bothering me and I've decided to get rid of it. One thing I did was go to the folder properties, go to that customize section, and set the icon to default. This worked for some folders, to my joy but it didn't work on some.

Another thing I discovered is the folders are only displayed like that on my particular user account, not on another one. I have tried deleting the icon cache or something like that, and I've used some program called Winbubble or something but nothing's been working. Any possible fixes or theories or whatever are welcome. A system restore isn't possible, as this, as mentioned, was a while ago.
