I recently upgraded my Solidworks Premium 2008 to 2009. Upondoing so, I am now unable to open all of my projects in PDMWorks. Ican preview the files and it shows they are there with the correctrevisions but when I try to Open/Check Out, I get the message"Error retrieving "(part #)" from the server. Do you wish tocontinue. If I log into the server and create a copy of the projectand then try to open that project, everything works as expected.Any help is greatly appreciated.SolidworksSolidworks Pdm enterprise Pdm
