I bought a copy of AVAST Pro a few weeks ago. It installed and worked fine for about a week, now it tells me it has an invalid license code.
I have read the support forum, watched the videos. I have ensured my date/time is right, I have ensured that I am entering the code properly, both by cut/paste and not getting trailing characters to entering it several times by hand. I am making sure I am running as administrator on a user account with administrator rights (Windows 7 Pro).
I still get Invalid license any time I try this. Help!
