Have you tried downloading at all from youtube? An error report is not created, but a few error messages show up for a few seconds then disappear. This was #3 of 3.

"Let's play Heroes 4 WOW [182] Flies in the Ointment 1":
[PYI-6420:ERROR] Failed to execute script 'main' due to unhandled exception!

but error log is empty
