Adobe workbench errors on checkin: Asset already exists / file already exists

[JosephDoggie]

Adobe workbench for Myserver checkin gives errors:  "Could not create the asset because the asset already exists" and/or "File already exists in global store with that name".  How does one fix this? 

This seems to especially happen when I change login to workbench user/configuration/"mode" etc.

I believe that "synchronize" in LiveCycle Workbench on the folder in question helps.

NOTE:  Closing workbench did not help, nor did a reboot of the server in question help.

If worst comes to worst:

Save relevant directories in completely separate windows backup directory path.

Remove all sub-folders from LC workbench (everything below the /1.0 leaf).

Restore directories from backup path.

This seems to ALWAYS work.
