Error code: -1609629695, Unable to produce frame.

Hi!

I have the latest After Effects and the latest Media Encoder - whitch is failing rendering all the time.

I tried all the tricks from the internet and youtube:
-updated the driver
-changed CPU to software
-rendered it to an other drive
-purged the hell out of it
-changed Bit Depth etc..
 uninstalled, installed and uninstalled again, and NOTHING WORKS.

It happens with every project, so I don't think suddenly all my imported footages were corrupted in any way.

Rendering from the render queue is working perfectly, but when I try with Media Encoder the first render sometimes! working, but never again (until restart). Please help me, I'm really clueless.
