I did a backup using HeidiSQL maintenance. Some tables were not created correctly. I believe this happens when the table has no data. This was a serious enough problem that my company has decided to not rely on HeidiSQL as a primary tool for working with MySQL (5.5). HeidiSQL is otherwise a very good tool.
Ads were blocked - no problem. But keep in mind that developing HeidiSQL, user support and hosting takes time and money. You may want to send a donation instead.
