Tunngle gone south?

[Silent Steel]

Hi all

Yesterday I decided to join the Tunngle but...
First I followed the instructions for registering, entered all my details and so on.
Then I was told I should shortly recieve a registration code by e-mail but up to now no activation code arrived...

Today I went back to the Tunngle site checking the FAQs and troubleshooting parts.
Found out there is a possibility to get a new activation code, terrific I thought so again I entered my details but...
when submitting I was told my "user" is unknown.... Of course it is - I haven't been able to activate it yet

Getting fed up with this nonsense I tried to register a new account but then I'm told either

1. my "user" is already in use...
or
2. my password is not valid..
(but yesterday I was told everything was OK and I should just wait for my activation code to arrive).
or
3. my e-mail adress is already in use by another account...

Good Lord.

Anyone knows how to solve this or should I just forget Tunngle?
Maybe the Tunngle doesn't want me to join - I don't know.
I'm stuck

Thanks for any help you can give

Regards
