FileZilla errors

FileZilla v3.63.2.1 on Win7, get the following error when launching:

Error loading queue

An error occurred loading the transfer queue from \Data\settings\queue.sqlite3
Some queue items might not have been restored.

And get the following error when closing:

Error saving queue

An error occurred saving the transfer queue to \Data\settings\queue.sqlite3
Some queue items might not have been saved.

I have tried clearing all databases within FileZilla, but I have not yet tried uninstalling and reinstalling FileZilla (need to make sure nothing needs to backed up first).
