error 220
This may already been solved by TT or addressed by others but I resolved the issue by moving (just in case it didn't work) the EPHEM folder on TT to a hold location on my hard drive while TT was connected to TT Home (you can do it with EXPLORE). Then disconnect TT from Home, shut it off, turn it back on and when it connects to HOME it will update. It's been working fine since.
