Simulink library browser shows "No blocks"

I can see all of the libraries, but no blocks.
I found the following posts, but they don't have a solution: http://www.mathworks.com/matlabcentral/answers/2981-all-blocks-missing-from-simulink-library-browser
http://www.mathworks.com/matlabcentral/answers/2782-simulink-library-browser-blocks-gone
I have tried: restoredefaultpath rehash toolboxcache rehash toolboxreset
I know others have seen this at our site, but no one knows what actually fixes this. Perhaps a reboot. I have tried logging out, but rebooting is not possible at the moment.
Thanks,
-Kevin

What do you see when you type "which -all slblocks"?

This may be related to bug report 673978.

Good find. I am unable to write in this directory, and don't have permissions to change/move/delete it either. Unfortunately, I will also have to wait for an admin-type to come in to modify it for me. We are using 2010b as well, so this is likely the issue.

This could be the result of a corruption of the library browser repositories. These can be regenerated by deleting or renaming the library browser information stored in the preferences directory.
Rename the following directories:
disp([prefdir '\sl_library_browser_repos'])
disp([prefdir '\sl_library_browser_favorite'])
Rename the following file:
disp([prefdir '\sl_library_browser_lockfile'])
for example, I renamed sl_library_browser_repos to old_sl_library_browser_repos.

Kevin: Have you tried Seth's suggestion? The MATLAB preference directory (prefdir) should be related to your user account, even if the MATLAB installation is shared, so that might very likely be the issue.

Yes, I tried this, as well as renaming/moving the entire .matlab folder as well. Thanks.
