New User/Received Registration Key/Appears Invalid/Help!

Hello Everyone!

Windows Vista user, downloaded Avast!, restarted in safe mode, this wonderful program found LOADS of stuff on our computer, when I went to delete them I realized I was not yet registered, did so, got my registration key, cut and pasted… You guessed it, I get a pop up window telling me that it is not valid. I checked the date on my computer and it reads the appropriate date. Tried calling tech support, they said they’d call back today and, as of now, I haven’t received a call.

Any ideas on how I can go about getting this sucker to fire up and finish cleaning this awful stuff off of our computer?

Thank you all, in advance, for your help and your time.

All the best!
