Please press the hyperlink "Collaboration Manager" in the left navigation and then press the hyperlink "Global Settings".
If you use the CollaborationManager on a server farm, every server needs the "CM_Temp" folder with the same path. You have to create this folder on every server per hand.
Fill in the Temporary directory a path to your local file system. For example "C:\CM_Temp\".
Set the "Continue Workspace Creation after FatalError to "Disabled".
Press the OK-Button.
