Sorry TylerVollan, somehow I missed your reply...
It could very well be that you are editing with Notepad. Notepad tries to save files with a ".txt" extension. So, even if you specify the filename to be "autoPrizes.xml", it could save the file as "autoPrizes.xml.txt". Make sure when you save the file in Notepad that you Select "All files" under "Save as type" (on the Save As... dialog).
Might not be the real problem, but better to check.
