I have just upgraded my iMAC to Snow Leopard and Parallels no longer works. I bought Parallels about 18 months ago so that I can use Windows 2000 and run QuickCAD which I am used to using. I have quite a lot of CAD files that have been saved on the Parallels virtual C: drive (they are associated with getting ready to apply for planing permission to carry out some work on the home I have just moved to and I can no longer get them). So, is there a free/low cost upgrade available to my version of Parallels or do I stop using Parallels and get a CAD package for the MAC such as Qcad. My gut feel is the latter but I need to be able to find my drawings on the virtual Windows C: drive
