This is going out on a limb here....

I have been reading the posts from people indicating a mirad of different problems. I honestly don't think that the problem lies within the programming of the plane(with a couple of exceptions), so I think that there might be a simple problem of downloads being corrupted. The server is very busy right now, as indicated by the flood of posts saying that they haven't received email notification for there purchase. This possible corruption, I think, could explain things like the PMDG Registration menu not working, the 767 PIC AIRAC not working.....So, perhaps everyone can post the Md5 Checksum and we can see if downloads are being corrupted.....
