Server Error

[mdzc81]

Both on the 30th of August and the 1st of September (today) I tried to change my domain from mdzc.x10.mx to mdzc.co.cc, and on both occassions, when I went to visit mdzc.co.cc, I was taken to a page my Anti-Virus deemed suspicious (I think it was a JS drive-by attack page).
Seeing this, I promptly changed my domain name back to mdzc.x10.mx (both times), however, the second time I did this, when i tried to visit mdzc.x10.mx, i was greeted with a server error.
What is this error and when will my domain be accessable again?

Hello Dear mdzc81,
Good Afternoon.
You site "WebTing" with only a login form is working on my browser.
If it is not working on yours, the reason might be that the browser cache is to be removed.
If you are using firefox..try deleting browser cache and hit a ctrl+F5
That will full refresh your page.

How bizarre, can I ask what causes this error? (just out of curiousity)

What about the domain name?

Thank you for your help and swift reply by the way
