Recently we have seen a lot of codes used to unlock our products being offered for discounted prices. Almost all of them are bought using stolen credit cards. These codes will all be blocked by our systems and you will have to try to get your money back from the seller, we are unable to assist in these matters. Do be very careful when you see a deal that is almost too good to be true, it probably is too good to be true.
Okay, I just testing the Delta A319 (CFM) and I didn't have any issues with pressurization.
Maybe something didn't go right with the update? If so, a reinstall might help.
Looking forward to hearing back from you.
