I am going from A12 on a non-intel iMac to A14 on a new iMac 27. Every project has happily made the up conversion, except for one. And, of course it is the one that I need now for a project. It is a large, 26mb, file of a building that I have done multiple tenant and common area projects in for the owner. I started this file as an import from AutoCad (BOOO) in 2006 so lots of upgrades. I have tried to open it several times and I get a message that it can't find server fe80. I have always used the local computer or the office server for project and library access, not an outside source. At any rate, I can get to the window that shows you what libraries loaded and what didn't then I click OK and then... Bug Report!
Any thoughts? I sent a file to Graphisoft but they are very protective of information if you didn't sign up for their maintenance program, even if the product is brand new.
