Windchill Workgroup Manager - issue changing workspaces

Question

PTC should have stated there was no support when I started the ticket, instead of when I finished the ticket ! ! !

I am using Windchill PDMLink Release 12.0 and Datecode with CPS 12.0.1.3

My workgroup manager is having issues changing and refreshing workspaces.
I may have saved files in the directory when WGM didn't want me to. But my IT department was demanding a computer shutdown.

Here are the errors messages that I face
An issue occurred while switching workspace. To resolve this issue, close any applications that might be using files from the workspace, activate the workspace that was active previously and then perform the workspace switching..
Skipped workspace refresh due to an internal error. Refresh workspace if needed.
Syncdown blocked due to WLD lock. Please close all CAD application/programs that might be using files from WLD, deactivate and activate the workspace again.

I'd appreciate any assistance with this.

Then again, I cannot believe this is the first error PTC has seen. There should be a concisely written rules of operation/recovery document.

Does the newer version of WGM use a different local cache method/structure?
