Tweet Attacks Pro II - Bug report/advise required

I have recently invested in tweetattacks Pro II, the bot is easy to use & easy to set up. However I am having an issue when trying to get just one account to follow, it currently follows about 20 people and then stops, completely freezes. The spec of my computer is easily good enough to run this (8 core, 8gb ram etc.) I had my account set to follow the followers of 20 large twitter accounts.

I am strongly considering moving to Tweetdemon.

Any advice or comments?

Best regards

AOD

I advise trying there own forum or contact the dev's directly on they're webpage.
