Hi, This new parts you will get in local cache directory location. You log call to PTC technical support they will help to resolve this issue. Another method is as follows: The cache files having file extension.wfcont The server side parts (Uploaded or check-in)name will start with sid_ and system generated number. The newely created files name start with lid_ and systen generated number. Copy this lid_xxxxx files to one folder. Rename files extensions to .prt and try to open in pro-e, same try for .drw & .asm. This process requires more time but you can retrive your data by this process.
