So, here is the story thus far:
1. Unsucessful GP RC6.1 install
2. Clean restore
3. Sucessful GP RC6.1 install
4. Connected to WiFi, Home Sharing working, AirPlay enabled, get error in subject
5. Read forums, say to install XBMC, says installing, restarts LowTide and no XBMC menu
6. I have updated nitoTV, Rebooted AppleTV, Restarted LowTide, updated All, and several combinations thereof and still get the error trying to install aTV2 Flash!
FWIW, I can get Weather, RSS Feeds without problems. It seems like nitoTV and aTV Flash just cannot install software on my box!
Anyone have any ideas?
