I was just about to fire up a stream using NVENC to see how it would run

as soon as i try to preview it shoots me an error that says "Encoder Initialization Failed!" the log file stated it failed to load nvEncodeAPI.dll.

any ideas on why it may be doing this would be appreciated.

Code:

Try doing a clean install, and then rebooting your pc. Not sure why these drivers seem to be breaking NVENC for some people.
