Im having the same issue as you Lunatic, I played a few days ago fine, now it says that for me as well and Ive patched already. Ive tried reinstalling the game, that didn't work. Ive also tried restarting game multiple times, didn't work either.
Found a new problem with all the new Uprisings, they will now instantly kick you out the minute you try to load into them. Fix this issue, i tried 4 different ones today and instant kicked back to Imp Fleet after trying to load any of them.
