corrupt DB or something else?

[Die Fledermaus]

I am consistently getting the following error

 I had my usb stick on my raspberry Pi fail during an update so I had to restore my weewx from my backed up files. I am concerned the DB copy I have is corrupt. and I will loose all my previous data. If I have to start with a new DB what is the best way to do this short of reinstalling weewx, and putting back the backed up files minus the DB.
