Explorer Crashing over and over again

[damovee]

 desperately need of help. i recently dragged a .aa file i downloaded from audible.com to my desktop. I then changed the name of the file. As soon as i did this, my explorer began crashing at an unworkable rate. The only thing i can manage to do before it crashes is attempt a delete. At this point a message pops up telling me it cannot because its connected to a program. I dont know what this program is. i wouldnt have enough time to delete it anyway. Is there any way i can manage my administrator files and programs from guest? thanks in advance
   
I need to add that this also happens in safe mode. I might try a delete in safe mode but the are so big, the file is not displayed

my explorer began crashing at an unworkable rate.

Would that be Windows Explorer or Internet Explorer?

any way i can manage my administrator files and programs from guest?

I would imagine your guest account wouldn't have the same privileges as Administrator. Does your computer do this when you log in as a guest? Do you have your OS disk?
