This error occurs when I try to check a file into the vault & keep it checked out. The file can be checked in & then checked back out. EPDM has been un-installed, the registry cleaned of EPDM & re-installed & the problem persists.

Has anyone had this error & what was your solution.

System is:

Dell T3500 quad core

XP x64

SolidWorks 2009 x64

EPDM 2010 x64

thanks
