Did a bad thing

I reformatted my hard drive and misplaced my computer number, which is required to find the registration number. Am I dead in the water? Does 3dfa have my purchase on file? I emailed them awhile ago and have received no reponses.

Your computer number can be found by doing the following:

1) Open 3DFA
2) Click 'Purchase' from the menu on top
3) There is your computer number

Go to the 3DFA website and Update Registration and put in your computer number and the e-mail address you originally registered with and you should get a new number in at most 24 hours.

Thank you very much
