I'm seeing the same crash with Elements 11 and Windows 8. I just get a generic "Adobe Elements 11 has stopped working" message. It's pretty random. At first I thought it was when I was viewing photos in Organizer one at a time using the arrow keys, and hit a video item, but it started happening on its own with no user interaction. It happens even when Catalog Repair shows the catalog doesn't have any issues (though a few times it's crashed and caused issues in the catalog which i've had to repair). My catalog is stored on a Drobo S drive.
I immediately opened the same catalog on a Win7 machine and it works just fine. Thus is seems the catalog isn't the issue, but that it's some interaction between Elements 11 and Windows 8.
Are others seeing this?
Similar to your problem, but it crashes during launch, not after a period of use. I posted this at DPReview to see if anyone there has some insights:
I just rebuilt my PC as the machine was suffering random hardware crashes. So I took the opportunity to migrate to Windows 8 (with a format and clean install, not upgrade) and also upgrade a few other bits, e.g Elements from 8 to 11. Most stuff works, but Elements 11 just refuses to start.
Running the Elements launcher does nothing (it fails before anything appears). Running the Editor directly from the Program File folder shows the splash screen, but then Windows shows a dialogue saying the app has stopped working. I've tried compatibility mode and running as admin (it throws a UAC dialogue, which is odd for an app designed to run as a normal user under Windows 8).
The Event Viewer shows the crash coming from the call to ntdll.dll:
C:\Program Files (x86)\Adobe\Photoshop Elements 11\PhotoshopElementsEditor.exe
My other software works fine, including Lightroom 4.3 and Reader XI, so it's not a general Adobe or Windows problem.
I've searched around, but there's not much help out there. There were suggestions to delete the contents of the User/AppData/Roaming/Adobe folder, but that didn't help. Uninstalling and reinstalling doesn't change anything. I even downloaded the trial version from Adobe to see if that was more recent than the DVD, but it seems to be the same version number (from 22nd September 2012) and suffers the same issue.
So, has anyone else got this software to work on Windows 8 Pro? If so, did it "just work", or did you have to do anything?
OK., after some more trying this and that: I have NIK installed as a plugin and it workes fine when I use the sharpener, as soon as I try and use define Elements 11 crashes. It worked fine under Windows 7. Outside of that Elements workes fine, both Organizwer and Editor. Might have to contact NIK.
Some more experimentation...
It looks like the problem is between Elements 11 and my Wacom Bamboo Pen&Touch. Unplugging the tablet allowed Elements to launch successfully! The organiser still hung importing a large folder, though...
Plugging the pad in after running Elements, and it all sort of works. I say "sort of" as the cursor seems to be quite unstable when using the pad... So is the problem with the Wacom drivers for Windows 8, or Elements integration with the drivers?

Seems like third party plugins like Nik and Topaz lead to issues with Organizer and Editor. You might need to disable them to use Organizer and Editor fully.
