When i try to open a rough cut I edited a couple of months ago. A lot of the files ask me to render them. Even when they dont have any kind of filter applied. When I render them, and the red marker on the timeline turns green. Premiere doesnt play the files. Only when using control+spacebar the files play out but obviously the framerate is to low.

That sounds like a support issue, as something is not installed correctly or something new has placed need components -- no idea what, that is why it is for support. Need in there well before the Thanksgiving break.

I rolled back to different versions of cineform, but its all the same.

It´s very strange indeed
