The legacy community forum is still open mainly for help on free products. Please search the forum, check the documentation, and the FAQ before you post. We use to answer every 48/72hs.
All customers are encouraged to submit a ticket to professional support http://support.extly.com. In this way, we can better answer and follow your issue. First Response: We answer all support tickets the same day (Monday-Friday).
In any case, please describe your problem in detail, and do not forget your PHP, Joomla and AutoTweet version. If you are still working with Joomla 1.5 (not actively supported anymore), upgrade as soon as possible to Joomla 2.5 / Joomla 3.0.
