Why do I keep getting TRANSIENT_ERROR when uploading to Youtube?

I found this in another google search result while searching for "youtube TRANSIENT_ERROR", it has fixed the problem for me, at least for now:

"TRANSIENT_ERROR is a common (and cryptic) error that is encountered CONSTANTLY when using the YouTube's multi-upload feature. Once encountered, all future uploads are halted and the user is left with NO CLUE of what to do. Searching YouTube's help yields no information even though this is happening constantly and has been for a long time. Almost all of the messages generated on YouTube are like this -- some lazy developer is stubbing off the code with generic error codes and no description. Overall, YouTube is half baked. I can't believe Google puts their name on it and allows users to encounter errors like that, and my other favorite {MAX_SIZE}.

So now, after my rant, let me tell you how to "fix" this: if you uninstall the YouTube Uploader (via Add/Remove programs) and then re-install it then the uploads will proceed. Problem is, it'll keep happening after 3-4 uploads. You have to continually uninstall/reinstall to use the multi-uploader. So the bottom line is, multi-upload doesn't work. You're better off to just upload one-by-one."

had the same problem. found the "solution": just leave it be and hang on. the uploader will just continue to do what it should do until it's done.

My problem is when i go to Add/Remove Programs it says "The application failed to initialize properly (0xc0150002)" so I can't upload onto YouTube or Add or Remove Programs at all.
