Cards not found

[metalb00]

Ok so i just got it goin and played a few games the other day on the beta server. for some reason when i try to load any deck i get the error in the attached file but its a variety of cards, like sol ring, arcane signet and others. ill change the effected cards and a new one pops up. im on the beta server played Saturday with no issues. deleted everything and redownloaded and no fix
