I have on my home computer the vw 2011 and I tried to open a file on the school computer which has the 2009 version of vw but it says that it can't open it. The message is something like this: "this is an file created in newer version or it's corrupted".
Does anyone know if there's an update so that it works both ways? Or is there some other way I could get around this problem, like saving the files in some other form?
