GPU Effects Error
I started a project on Monday, and everything was working fine. Then on Tuesday I have opened the same project and started getting the "GPU effects error". At this point, I can't even use AE anymore.

So the problem is not the hardware, like the weak GPU (I have 2xQuadro p4000 cards).
I should mention that after finishing work in After Effects on Monday night, I have installed Octane for c4d demo. It doesn't make much sense that Octane should cause this problem, but that's the only thing I can think of.
I have tried uninstalling and reinstalling drivers, tried different versions of After Effects, I got rid of Octane of course, but the problem is still there.
Any ideas how to fix this?
