Thanks for that Jim, I have the same problem I even uninstalled it, downloaded it again, worked once then got the invalid ctf file again. :BigGrin:

 

Hi

Yes, it caught me out several times, I did as you then went looking for the solution.. no mention of this on the AVG website..

You may have to delete the CTF files again so keep it handy on the desk top.. bit of a pain.. but it works..

Jim

 

is this the 'free' version or the 'paid for' version, Jim?

 

Hi John

The FREE version,

I think it only affects Version 8 .. quite a bit about it if you Google..

 

If the above procedure fails..
