When i installed .8 on another website fresh, it installed with no problems. but when upgrading my current forum from .7 to .8, i get a note at the bottom to upgrade my database, then i click "install" it attempts to upgrade the database and i get this error.i never enabled full text search in .7, so i re-enabled it, and still got the error. However, i do believe its harmless. so im not to worried about it. i just want to know if it upgraded other aspects of the database despite the error message.

I've moved the forum http://www.eculinar.ro/forum/ to another server. When I try to search something, I get the following error:

System.Data.SqlClient.SqlException: The COMMIT TRANSACTION request has no corresponding BEGIN TRANSACTION.

Any idea to solve this problem?
