Installed the 64 bit deb package just fine. TV starts, but an error "Not ready. Please check your connection". Unable to login to my Computers and Contacts. Version 12 was working fine, just a few minutes ago.
Well the problem is TV does not cleanup after it's self. The solution was to remove "all" istances of TV. Remove the configuration files etc, and re-install TV 13. After that drill, everything appears to be working correctly again.
