I'm experiencing a lot of crashes connected to OpenGL previews of materials. As soon as i turn it off, it works perfectly. Also material preview generation quite often freezes C4d. If I turn that also off, no crashes at all.

Yeah. Purchased today - still the same This is very, very ugly - I purchased a product that I can't use and no warning was to be found anywhere. My subscription time is passing yet I can't use the product. I expect some sort of refund - license extension or something.
