"Unable To Find A Valid License" (Code 315306)

Technical Support

I have played this game for about a week now without much trouble, until this morning.
Now I’m getting this “Unable To Find A Valid License” Error Code 315306.
I have updated the Battle.net App and scanned and repaired the game, but I am still getting the same error.

Having the same problem and I was just playing earlier, less than a hour ago… Blizzard is circling the drain of corporate life; they better get their stuff together.

Had that too. I reset my network card (in terminal), restarted my computer and then it fixed itself.

Okay, so I uninstalled the game and reinstalled it, which seemed to work.
