So we upgraded to SW 2014 SP1.0 and EPDM 2014 SP1.0 about two weeks ago.  Just today, one of the machines cannot open any files from the PDM.  I can move around through the PDM and view the files, but when it comes time to open them using solidworks (by double-clicking the filename), solidworks opens and then hangs and crashes about 30 seconds later.

I get the error shown below in the picture.  I've taken the steps to re-install SW and also did a repair on the EPDM add-in/client program.

Suggestions?  I know that EPDM integrates with Windows, so could the explorer.exe process be an issue?  (When I install EPDM clients, I generally close the explorer.exe process during the install, and then restart it when the install is complete.)
