I have been having the same problem for months. I can't be a presenter on my computer running XP and IE8. I gethe same error. Probably having something to do with loading the exe from within the web browser but I amm not sure. A while back (when Nefsis first came out) I could revert back to IE7 and everything would work, but that couldn't stay with IE7. A fix/workaround would be nice.
