Error 205

I've tried signing in and out
I've tried clearing SLCache
I've tried running the command they suggest on their website
I've tried just booting the program without being signed in, and then signing into the programs

I've tried making a new account, clearing the credentials on my computer then installing from the new account with a new sub subscription

Any help would be great, I really need these programs for my mentorship, I am desperate here.
