What I did was :
1) Go to account settings on your youtube page, then click to link it to google+(which appears to create a profile, if you don't have one).
2) Go to advanced account settings(youtube.com/account_advanced), and click "change or add password"(it redirects to google accounts, for your new [email protected], and sets a password for it).
3) Change the login name in xbmc youtube settings to the name you see under advanced settings on youtube.com/account_advanced(like [email protected]), and then input the new password you set above.
4) Voila! You should now be able to login, and all your existing subscriptions should be there.

(Obviously change user-name-1234 above to whatever your username becomes).

Could it be related to the fact that I'm trying to download a VEVO video?
