Yikes...what a fuckin nightmare!
And I thought I was having a bad day...
UW...I see your old pals are still at it
I agree with the others Yauhen...your first step is to get a new host immediately. Sparky aka cd34 is a great host from what I'm told
Looks like you might be screwed on the domain based on the Whois information

But, domains are pretty easy to come by. As a matter of fact, given the circumstances...I'll give you a domain if you need one to get you back in the saddle again. I just renewed some at my registrar that I'm not using...you're welcome to one of em
Best of luck to you...again, first thing is to get a new host!
