simulink library browser blocks gone

simulink seems to have lost the link to the library browser blocks. The library names show up, but no blocks are in them. Any suggestions how to reset or fix this?

There might be a user-written file on your path.

I would go for the classic:

restoredefaultpath
rehash toolboxcache
rehash toolboxreset

If this does not help, execute:

which -all slblocks

It it returns a file outside of the MATLAB installation folder, try removing this file from the path.

same thing possible customization of the Simulink browser:

which -all sl_customization

and remove from the path anything which is not shipped with MATLAB.

no joy. results from 'which -all' commands below. Right clicking and opening the libraries brings them up in a simulink window, but no blocks in the browser. This doesn't seem to affect older versions of Matlab.

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.

hi Seth Popinchalk When i type sp([prefdir '\sl_library_browser_lockfile']), there is not anyfile like that . everything i try but i cant fix that problem . , please if anybody can write detailed answer it really helps me. the same problem again and again. The problem is

 "Error evaluating 'StopFcn' callback of block_diagram 'Single_Rotor_Example'.Library was not found"

i try everything icant solve
