Error message given with almost any youtube video link, won't even complete "parsing"

No error message, you paste link, it notifies "parsing" for about 30 sec & follows with a the triangle of death saying "error" has done it to almost every youtube video in the past week. Used to work fine, even uninstalled & redownloaded, re-set wifi, the whole 9 yards, updated, it simply won't work. & this is after I paid & inserted activation code even, complete BS.
