'Failed to execute DB job' Error Message

[i2w8am9ii2]

I was paper trading this morning, with no problems for the first two hours, then all of a sudden, every time I tried to enter a trade using Chart Trader, I kept getting 'Failed to execute DB job' error messages. I could not enter any trades from that point on and none of my trades would log the trade statistics from that point on.

Screenshot attached.

Please advise.

Hi Zachary,

If I do a database repair, will I lose the ATM Strategies I created, or my workspaces or templates or anything else?

Hello i2w8am9ii2,

A database repair will not delete any of your data.

[i2w8am9ii2]

Great. I appreciate the info.

I followed your instructions and at first I got a message saying that the database was successfully repaired, so I pressed the 'OK' button.

Then I saw a dialogue box that said: "Failed to compact DB."

Please advise.
