Back when I first converted to the subscription system I had all kinds of crazy errors like that.
Most of them settled out by a couple of reboots and / or waiting overnight for Adobe servers to sync properly and update their database (I guess), because they went away eventually with nothing smart done on my side.
Don't mean to insult, but have you tried rebooting?
i still can't go to my develop module.
Error message word-for-word, please.
