I just upgraded from 3.8.1 to 3.8.3 but now I cannot connect using any of my database connections. I'm getting the error "Error while trying to logon to database : <drivername>". This seems to be the case for several different drivers including Oracle Thin and HSQLDB in-memory.

Double check that the drivers are all still configured correctly and the JARs supporting them didn't get erased when you upgraded (I don't know where you put them).

Yes, the drivers got deleted. I have the one I want setup now. I suppose I should reinstall to get the rest of them back.
