Hi.
Yesterday I chose to upgrade my Avast Free Antivirus to the Pro version, after receiving the "one time offer" for only $9.99.
Downloaded the license file, activated it, received confirmation, Avast was happy, i was happy.
This morning, however, right after Windows 7 Ultimate 32bit booted up, i keep receiving this message, over and over again, even if i close the window or let it check online for solutions - it keeps poping up and the a.v. core wouldn't load

This is what i get:
-----

I'd like to think i did not do a mistake by putting my trust in AVAST (which, btw, i use since 2007 or so), especially taking your offer....
Please advise. I really want to have the a.v. working properly again.
Thank you.
