Okay well, here is the way I went about fixing the errors. Backup the original skin. Then fix all the errors that you can with skin studio. Save and reapply the skin. Then, look at it with the skin errors fixed. Open windows, check the start menu. See if everything is still lined up right and all the pieces present. If they are not, then you have to find out which error was incorrectly fixed. If you have a tab image missing, or misaligned, then erase the fixed skin, reload the original, and look at the error associated with the tabs. It can be a bit tricky fixing all the errors. But, I've done it on my skins.
