If you see the above error message in the DBTuna log files, or somewhere in the User Interface, then it probably means that one of the MySQL tables (where DBTuna stores it's data) has become corrupted. This sometimes happens on Windows if there was a server crash, unexpected shutdown, or a hard disk problem. 

 

Luckily it's an easy one to fix, you just need to do the following:

 

1.       Open up a cmd.exe 

2.       cd to [dbtuna install dir]mysqlbin

3.       Run startClient.bat

4.       Run "use dbtuna"

5.       Run "repair table statistics;"

 

Here is a screenshot of what it should look like:

Hopefully this will resolve the problems for you without needing to do anything else, but if not do not hesitate to contact technical support.
