The software needs re-installing, it got moved because it is a software issue, your best bet is to re-install Pro Contractor Studio and see if you can get it to work (files corrupted).
just got off tech support from CAD software support, they say they are sending me an e-mail with a link to download the "file that they claim should have come with windows 7"
Installing this (for the correct bitness of your program) should suffice to fix that error at least. I suppose that those drivers are included in Office, but they're likely not part of Windows itself.
