Tweet Attacks AC errors

I'm getting a lot of the following error when trying to create accounts in TA AC:

URI: The hostname could not be parsed.

Is this a proxy issue? I just got 25 new private proxies from a reputable supplier and I'm only trying to create 100 accts.

Mostly thats twitter server issue but try contacting support http://tweetattacks.com/support/ and give more details and screenshots, my staffs might find something.
