Greetings
This morning I awoke to an error message stating that I needed to put in my license number.  Having used AVG for 5+ years with no issues, this was news to me.  A quick search told me that a fresh install should fix the problem.  I tried to repair, which failed.  Then I tried uninstalling and that failed.  Finally, I tried installing a fresh copy and that failed as well.

This is all regarding the AVG Free version.  Any help would be greatly appreciated.
