Sims 2 University Registration Code Problems

I've had Sims 2 University since I bought it when it came out. I was very young and irresponsible so I didn't write the code down, we moved when I was 11 to a new house and my dad put some of my stuff in storage. I'm pretty sure that the manual for Sims 2 Uni is in a box somewhere in storage and I can't get it out because he won't let me go and see.

It downloaded fine on my desktop when I got it, so I went into my registry files w/ some googling help and I was able to find a code (I think) through there. I didn't find it under ergc and Data though. My desktop is a Windows Vista and I found it under "Registration GUID" and I don't know how to decipher the code. Instead of a 20 letter/number code, it's 32 letters and numbers and I don't know which ones to use! Could somebody help me please?! 😕mileyfrustrated:
