Cannot "register" TMGENC Express Trial!

[Yo]

I just downloaded and installed the TMPGENC Express trial. I was surprised that, when I started the program, it said I need to "validate" or "register" it just for the trial.

I went online, clicked the button for the validation, and immediatly got a message saying the trail had expired.

Strange that it could expire, when I installed it the same day, and never used the program before.

Anyone know what's going on?

Also, how do people like the Express version, as compared to the Plus version, etc. It certainly sounds good from their web site, but software often doesn't work as advertised.
