I am experiencing this -blam!-ing stupid thing also, i have done all they said and tried calling for two days straight, in the end I demanded a Refund for the expansion pass however... yes you guessed it. They aren't allowed to give me a refund 'because it's not faulty' IT CLEARLY IS. ESPECIALLY IF IT WONT -blam!-ING WORK INGAME. Update: Only thing I could think to do was Trade in my disc version and spend money on buying the Version from their Store. So that the add-ons are compatible. Still annoying as hell and money wasted.
