I searched for a solution for this problem and didn't find any, till one time when I tried to register again and I saw this:
At the end of the address line there was written "error=UNVERIFIED_PAYER_ID".
Then I understood why I cant register, I have to verify my paypal account.
So if you had this kind of problem and didn't find any help, you may want to look at the address line.
I wonder why second life staff couldn't just put that massage in the page and save me and others a lot of trouble?
