Hi dmrodes

The use of Windows 7 makes no difference to the operation of BIAB - have you looked along this toolbar starting with > New > Open etc the icons for .MID and .WAV should be there if not go to the righthand side and click on the small arrow which brings up the Add/Remove menu and see if they are checked and ensure they are

Hope this is what you are looking for

Brian
