Updating Lens Profiles Database

Question

I am trying to do an automated photomerge with Photoshop CC on a mac but as soon as the photos are in the document the process of Updating Lens Profiles starts and it just doesn't progress more than 15%. Waited fo a few hours with no success. Help!

Thanks Ssprengel
Are you running Photoshop as Administrator (right-click Run-As or a property of the shortcut) so that it has full access to the Lens Database folder(s)?
Yes.
function(){return A.apply(null,[this].concat($A(arguments)))}
Have you tried resetting your Photoshop preferences in case something is haywire with them?
Yes, bij pushing Alt+Ctrl+Shift immediately after starting the application.
function(){return A.apply(null,[this].concat($A(arguments)))}
Have you turned off OpenGL in your GPU settings?
Have you run a ScanDisk or Disk Check on your system drive and any scratch space drives?
Yes
function(){return A.apply(null,[this].concat($A(arguments)))}
Do you have any printer-drivers that point to network printers that aren't online or that you can't attach to?
Do you have any mapped drives or remote-shares that you are attached to that aren't online or inaccessible?
No.
After resetting the preferences as described above it "just" took 4 minutes to update the database cache. After restarting, however, the cache apparently needed updating again.
There seems to be a preferences or settings file that can be deleted in order to force PS to create a new one. But where exactly can it be found and what is it called? (Win XP SP3)
