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