P: Cannot use Slideshow, get "An error occurred when attempting to change modules"

The slideshow module in LR 4.3 doesn ́t work.
When I click on "slideshow" or "book" there is a dialog window telling me, that there is an error at trying to switch between the modules. Ok button, nothing else happens, grey instead of the module.

I ́m using LR 4.3 on Mac OS 10.8.2

I tried the last Version of LR, but there ́s everything ok.
A reinstall of LR 4.3 doesn ́t help.

Please help/ fix this problem.

This should be fixed in 4.4.

Need 4.3 for my camera support. I can't see anything about this in the 4.4 release note 😞

It's marked as In Progress, so yes they're working on it. Hopefully it'll be fixed in 4.4, but you can roll back to 4.2 for now if it's causing a problem in your workflow. Just uninstall 4.3 and install 4.2 again. You'll find the download links by googling "Lightroom 4.2 download".

what's going on? how long do we need to wait until there is a fix or a work-a-round? Has this even got an official ticket, are Adobe working on this?

There's more on this thread in Lightroom's forum:

OK.... well where can i download lightroom 4.2 to get it working again?!

Hi, Had same problem. I couldn't find a fix after a few hrs so deleted Lightroom 4.3 & reinstalled Lightroom 4.2 & I'm back in business again.

Hello, I have the same problem. Everytime I click Slideshow, I get this error message. I have tried this with empty Catalog and it didn't work. So there must be some error in the App itself.
