Matlabpool doesn't open: No public field IsStartupComplete for class distcom.in​teractivec​lient

In Matlab R2012b I get the following error message when trying to open matlabpool. I'm on Mountain Lion, Macbook Pro Retina. Anyone have a clue how to fix this? Google doesn't return anything!

>> matlabpool open
Error using matlabpool (line 144)
Failed to open matlabpool. (For information in addition to the causing error, validate the profile 'local' in the Cluster
Profile Manager.)

Caused by:
    No public field IsStartupComplete exists for class distcomp.interactiveclient.

Undefined function 'validate' for input arguments of type
'com.mathworks.toolbox.distcomp.ui.desk.ProfileDesktopMenuProvider$10'.

It's most likely this:

Followed the instructions. Now Matlab won't even open... Lucky I did the backup.

You should probably call support next, then. Something else might be going on.
