Tech Question: Help

I have a problem. As I'm a analog guy living in a digital world, I have a little problem way over my head.  Last evening when it was time for me to enter my receipts into my QuickBooks program a box appeared.

QuickBooks has a problem in reading this registration file. You need to ask your system administrator to REMOVE this file and re-install QuickBooks.

c:\Programdata\common files\Intuit\QuickBooks\qbregistration.dat

Problem is I cannot find this file. Even if I did I hate to think of the results if I attempted file removal. What worries me is the thought of losing six months to a year of my financial records. This sucks.

Any ideas?
