I just Downloaded the new version of CAV Beta 1.1 but cannot activate it. I had the same problem with the first release. It tells me Iam unable to connect to the server, If anybody has a solution how to fix this Please let me know.
G’day,
As an interim measure, if you are running CPF, do a right click on the Launch Pad icon, click on PERSONAL FIREWALL - ADJUST SECURITY LEVEL - ALLOW ALL. While it is disabled, do the install and validation and once completed, reverse the lowering of the security level described above.
It a cludge, I know, but others have reported that it works, and causes no issues once completed.
Hope this helps,
