Using 2015 SW sp2.1 and PDM workgroup. I cannot open "released" drawings; previously in 2014 worked fine. Something in 2015 changed how the drawing Rev reads the rev from PDM and tied to the "released" lifecycle status. The parts open fine but the drawing doesn't. It yields "An error was encountered while trying to open your file. Contact Technical Support for a possible solution." If I create a part and drawing, delete the rev link from the drawing, check it in, and release it, it will open fine. I can open "un-released" life cycle status drawings fine. It just happens once I bump the rev and change the lifecycle status that I can no longer view the drawing. I cannot be the only one with this problem. My VAR and Solidworks are still working to find a solution. Taken almost 2 weeks. Thoughts? I appreciate any help and thanks in advance!
