Compiled Error: MainData Corrupt?!

Decided to make a new topic, since I found the problem, basically, it says the maindata is corrupt from a compiled project, and I took a screenshot (made it a development build)

or a direct link:

It doesnt matter how many times I compile it, it still comes up with that irritating message. Any ideas?

Drop the support team an email. Let them know the serial number you have, and more details, such as the version of Unity, the OS version you have etc. There should also be a Player.log which you should send in.
