deactivated packs

hi, i dont know if im in the right place for this, but my packs arent working. i have like 10 packs, all bought like 2 years ago. and now, the past 4 months, they say 'deactivated'. im frustrated, i deleted all my mods, repaired the game a million times. but nothing works. i dont know if anyone can help me. theyre downdoaded, and beofre a few months ago they worked perfectly fine.
