Seems Manage 2014 when opening a Native revit file takes forever, the files I have been trying to open were done with Revit 2012, I havent been sucessful opening one yet (loose patients). Manage 2012 and 13 open the files fine.
When trying to load a box pops up and is flasing through REGENERATING and UPDATING REFRENCES that keeps going and going.
I don't believe you can do today's job with yesterday's methods and be in business tomorrow.
