Question

Please help with CONTRIBUTE Error 148:3

Answer 1

When something works one day, but not the next, then something has changed. You task is to find out what has changed.
It can be something behind the scenes, like an OS update, that kills the video, or the audio driver. It can be major, like installing new software, that does something to existing software.
First thing that I would do would be to get the very latest video and audio drivers for your system.
If that does not work, then you might wish to look at Restore Points, going back to when it last worked.
There are some other things that might give you a clue as to what is happening, when PrPro does not open. This ARTICLE might give you such a clue, or clues. Or, it might not, depending on what is causing the failure to launch.
One other thing to look at, and think about is what is PrPro trying to load. VST's (often added by other programs, especially Audio programs) can bring PrPro to its knees. Watch the little line of black text, as PrPro starts to load. What is the last line, before it disappears? You might have to point your video camera at the screen to capture what is being loaded, as it can go by quickly.
Good luck,
