reversing ATM - error

[Lucinek]

While running my reversing ATM, after several trades (cca 20 trades) NT show an error message:
Failed to execite DB job 'StrategyUpdateJob'.
Array for inserted data is too small. Try to insert less amount of data.

(Second row is my own translation from czech language, so it could sounds slightly different, but meaning is important, not exact transcription)

What is the reason?

Lucinek, the error points to a corruption in your database file. Please try to disconnect from open connections (File > Disconnect) and go to Tools > Options > Misc and Repair your DB (database) - then reconnect fresh and see if the issue has been cleared up.

OK, I'll try it. L.
