Works OK for me with SW14-SP5 & SW15-SP2.1
Run the SolidWorks Rx > Diagnostics tool to check for problems.
Opens fine for me as well.
Try restarting your computer if you haven't already.
Ran Diagnostics on both SW 2013 and SW2014 as suggested by Kelvin. SW 2013 showed possible video card problem, Same with SW 2014. updated video card driver (1st time) and 2013 diagnostics showed no problems, 2014 still didn't like the driver. Updated video card driver (2nd time), 2014 still not happy with driver. Same crash problem exists as before.
Re-started computer both times, no changes. Will keep trying. Something will turn up.
Local SW reseller opened the same file and had no problems. They did a pack-n-go and sent it back to me. Opened the file in a remote location with no problems. Did a pack-n-go from there to the working directory. Opened the file again. No problems.
Maybe it's just a weird bug that crops up from time to time. I do remember that at times a pack-n-go will somehow clean up the files.
Thank for your suggestions and assistance.
