Hi. I was getting the same messages most of the day. I have dial up and can't really get it, but my friends place has highspeed and can load up O.K., but even on hers it was disconnected at times.
Also after installing quicktime-restart your computer.
Hang in there & good luck with viewing your friend. The cam is pointed directly at the man..I saw it for a couple hours tonight...
check ya laterzzz
