What I am saying is that I notice of all the plugins you mentioned not working suddenly are exclusively GPU accelerated, but you're saying some non-GPU accelerated ones are having the same issue. You've made a post both on PixDither and on B.Carve though which is adding to the confusion. Another user on another one of my GPU-accelerated plugins seemed to have a similar issue here.

One way to diagnose the issue is to upload the log file somewhere to see what's going on:

Try uploading the `.crash` file somewhere for me to inspect. In the meantime I might suggest updating/reinstalling your graphics drivers and perhaps even the latest Visual Studio C++ redistributable(the x64 link in this case) in case that is a possible cause.
