Camera rotates instead of moving (AE CS6)

It's more likely that your graphics driver settings are messed up after the crash. I would go into the device manager, completely uninstall the driver, reboot and have Windows reinstall it automatically. And yes, of course you can simply delete the prefs and AE will create fresh ones as well.

Feel the need to jump in once again - the camera was not the only issue, now the rendering sporadically stops writing output file. I have a feeling this is related to the crash I mentioned.
Just a quick question: does resetting the preferences in AE works same as in Photoshop? Or would there be need for installation repair?

What is funny about it, is that when I set initial keyframe, then scrub, pan the camera and set destination keyframe, the rotation is appearing at initial keyframe and not destination.

Interesting. A simple sideways pan should not expose this behavior indeed. Have you updated your graphics hardware or driver recently? Maybe it's some internal error with soem matrix functions. Does everything look okay inside the E3D editor?

Just checked few old animations and moved the camera. The problem persists - where previously camera was panning sideways it now only rotates. Since older projects use 2D planes as 3D objects, I don't believe this problem is caused by Element 3D.

It's calles gimbal lock and a simple math problem. Add at least one more keyframe that slightly curves the motion path to stabilize tha interpolation.

To figure out the problem, we need to see embedded* screenshots showing the modified properties of Element and your camera. Select both layers, press the U key twice and drag your screenshot to the reply field on the forum, then describe your workflow in detail. It is probably just a user error.
