After installing for the first time ever, a message appears saying my trial period has expired. What did I do wrong?

Probably nothing!
There have been a few reports of the two-month trial failing to activate upon installation. It is not clear what the cause is, but the most likely candidate is an interruption in the Internet connection during installation.

In any case, the solution is simple: send me the email address you wish to use to activate the trial and I’ll send you a trial activation code as soon as possible. When you receive your code, follow these instructions.
