elements doesn't start, only produces an error message "workspace coud not be opened"

Hi all,

I'm experiencing a strange problem: When I try to start Elements, I get an error message (see attached picture), saying: workspace could not be openened in "" because the file does not exist.

I reset the settings by pressing alt-shift-cmd and checked the workspace setting by pressing cmd-alt on startup, nothing worked. I deleted and uninstalled elements, deleted the windows cache files, same problem.

Fun fact: in my second account on the same machine, its starts up! Both are admin accounts.

Any ideas?

Thanks in advance!

Carl
