Did you do as it says?  "Check your backend logs to determine whether 
your capture cards, lineups, channels, or storage configuration are 
reporting errors."

If you don't see anything interesting in the backend logs, then please 
post a complete backend log (not excerpts) and we can help you figure 
out what's important.  Shut down all of MythTV (backends and frontends), 
then clear out any existing log files, then start mythbackend, then 
mythfrontend, then attempt to start Live TV, and then shut down backend 
and frontend and post the (now short, and containing only relevant 
errors) log files for the backend and frontend.

BTW, you didn't see this message go through because gmail doesn't show 
messages you sent until someone replies to them.  This should prove that 
the first went through.  That said, if you think a message didn't go 
through, you should check the mailing list archives:  
http://www.mythtv.org/pipermail/mythtv-users/ (and, specifically, for 
this month:

where the most recent ones are at bottom).
