Word 2003 Doc Opens With Weird Symbols In 2007 Please Help!

[speeddevil45678]

Hey everyone. Ive been having a real hard time trying to figure out what went wrong with this document. I moved a few files for my buddy and promised him everything would be just as it was, but something happen and his 2003 word document now has a bunch of weird symbols when he opens it with word 2007. Ive read a few things on opening it with notepad and all that but nothing is working and im really scared cause this doc means alot to him. Ive even tried the 2003 word viewer application and even that opens it with those weird sympols. There are two types of the file, a 97-2003 file type and also one thats a TEXT RICH FORMAT. Can someone please help me out and get his text back to original form. Thank you very much.
