I am of not much help but have similar problems. I get message: unable to play from WMP 11 – could not connect to Firefly at all. Tried from laptop and Firefly was fine! Downloaded slimbox but no luck although that seems to come up in the log file of Firefly…. It is all a big puzzle to me and all that really works is the internet radio.
I have downloaded the upgrade without problems but it did not solve the firefly problem.
Had firewall down and Norton anitvirus but no luck.
Any one any idea?
I did not get a response from Roku.
Thanks!
