Problem activating account

[Morwen Bunin]

I have invited to friend into SL, they wanted to have a look at it after I told them about it.

So they tried to create an account.

They selected a default avatar. Entered a name for the avatar that was available. Entered a valid mail-address, a correct birthday (1974... so should be old enough :P), a password. A security questions was selected and an answered to it entered. All entered information was okay as the "green okay mark" behind showed.

But after pressing the buttion to activated the account nothing happens. The text "activating" is displayed with little round symbol indicating the computer is busy.... and so it stays for hours.

They used two different desktops, with Firewall/Anti-virus software off and on. They tried it on a laptop.They even tried it on a computer at work (during a break and okay from the systemadministrator there). But always the same result....

Anyway an idea what is going wrong here? I really would love to show them around in SL....
