I can't seem to be able to locate the file in which to copy the file to deactivate the XP Cap...if anyone could help me out I would greatly appreciate it...Thank you very much.

Its very simple, just put the file in your "override" folder and the xp cap will be removed ^^

BEWARE: make a backup copy of your override folder before doing this, so you'l not take the risk of screwing things up.

Thank you very much...I hope it worked. Will it notify if it works or not, or do you just have to wait until the time that you would exceed the cap? I am using a Kensai as a main character but am going to dual class him as a mage in a couple more levels and I want to make sure he can still get high level spells....Thanks again!
