Version 6.56 build 3339 won't license

[mickeymouse]

I have just recently installed version 6. I was using 3,4, or 5.
When I try it says cannot find server.

PS my email address has changed from the day I bought the license. I can send it in a PM

Yeah, you can't register old versions because the security protocols they used are no longer used on the internet. A work around is to install and register the latest version, then run the old version.

Or you can just run the latest version. Your choice.
