F@H Not connecting at all

[SmoulderingCircuits]

F@H was running fine for me in Lubuntu, then over the past week or so it has been freezing more often than not when I complete a WU and won't send it. Now I have had a few messages saying 'local client ended unexpectedly, restart the client?' and after a few attempts restarting wasn't doing anything and uninstalling then reinstalling hasn't done anything either and have even unplugged from the wall to make sure there is no stupid junk being stored in the ram between sessions. So my main rig is now effectively useless until I can get this sorted. Any ideas?

I've made a new client but that hasn't worked either. Really stuck.

UPDATE:

Managed to get it to connect but still keeps freezing.

Got this error:

[font=Monaco,]ERROR:Exception: Error executing: 'PRAGMA synchronous=NORMAL': database is locked[/font]

Reinstalled now...
