8830 Help....

Hello...I'm fairly new to the blackberry game, but I do have a problem.
I cannot watch youtube on my 8830 from verizon. The error message I get says "The protocol specified is not supported by the handheld, please try a different URL." WHAT IN THE WORLD DOES THAT MEAN?
Also, I am currently running on V4.2.2.196, and would like to upgrade to V4.5, where could I find it? The verizon website has V4.5 for the curve and pearl.
Any suggestions and/or ideas would be greatly appreciated...and please take it easy on me lol.... :)
