MS and it's products fail you? Found some corrupted documents from MS's applications? It's an easy deal. Call them, open a support ticket, do whatever make sense to ask them for support. MS is a big company. And you've spent a lot of money only to get the license so you can get the applications working. Pretty sure, they will overcome the problem as easy as they ripped your money.
But still you came to us. I'm not MS's associates. I don't even use the products. It's not a shame thing if I can't fix the problem. Can't read the source, though. Don't blame me for somebody else's sin.
