Microsoft FAIL today, as Ben came to me and told me that the game was asking for him to "insert Flight Simulator disc", whatever the fuck that means.
I got it fixed, but suffice to say it wasn't easy or trivial, and it was due to design/authentication errors which have existed for many months, and which Microsoft has made no effort to fix.
Basically fixing this took 3 steps, including diagnosing what the fuck even happened, which wasn't easy, given that 1990s-esque "insert disc" message was all the information Microsoft felt we deserved.
As you might have guessed, there was no actual disc we needed to insert, nor did we have to even download anything further.
Microsoft really has become terrible in so many ways.
