We have just upgraded to Creo 2 (from wildfire 5) and are having issues connecting to our Windchill server on start up. We have Windchill 10.0 M040 and Creo 2 M090.
We Log into Creo 2 the first time, set up the server details using server manager. The second time we log in all is well, server has connected and we can see and use the workspaces. The third (and any subsequent log ins), the server has disappeared from the list of servers, and we have to manually log in again.
Windchill works fine in an IE browser.
I have deleted the .wf file in my appdata/roaming/ptc/proEngineer/Wildfire folder, and deleted the 2.3 file in appdata/local/ptc/creo/platform folder as instructed by our USA counterparts, but to no avail.
