Purchased Personal Firewall & downloaded it & it tells me it is the trial version-Where do I get the key to register it? I tried using the oh-so-long serial number but to no avail. (Tried to copy & paste serial #).

Hi

Hi,

Take a look at the FAQ page that shows you how to copy and paste in the serial #

It's about the 3rd one down.... How do I register using the license key?

If you are still having a problem contact Tech Support via the Support Center:

(Raziel, I think he is saying he already purchased it but has problem getting it registered)

Hi, sounds like you are on the right track. Have you managed to load your license key OK now?

When the trial version starts it will display a window like

From your registration email copy the full license key, all five lines exactly as it appears.

Then in the Lavasoft personal firewall Enter Key window press the Paste button followed by the OK button.
