I'm trying to open an older Revit architecture 2014 project in my newly downloaded revit LT2017. I get this error message: "An unrecoverable error has occurred. The program will now be terminated. All of you data has been recently saved, so there is no need to create recovery files."
I can open the sample projects as well as families that were created in 2014, but I can't open the project created in 2014.
Any advice?
Thanks,
Rob
