Thanks for your answer.
I should've used the search and like you suggested i should've just called the customer service. For some reason calling for registration didn't even cross my mind. I've never had to call anywhere to be able to use legitimate software and it's also not a first thing to do for a non native english speaker to call long distance to other side of the world.
Maybe I was just depressed by the fact that when i contacted customer support regarding a problem with installation i also didn't get an answer. Now when i read the email technical support page better i noticed that you can't get support for unregistered product. That's pretty damn helpful if you first have a problem installing the software and then registering it..
Well, enough of this already. I hope my problem will be solved with a phone call. Only couple of hours left and it'll be 9PM in the Land of the Free.
BTW, my ISP does not filter anything, i get a lot of spam and they end up neatly in junk email or spam folders in outlook, depending on by which program (f-secure or outlook) they were tagged as spam.
