I just installed CS4 correctly on my machine and Premiere is constantly crashing every 10 minutes or so and I can't tell what exactly is causing the problem. It happens when I'm rendering, Playing video of timeline and sometimes when I'm doing nothing at all.
The message reads Premiere Pro has encountered an error and needs to shut down. Either that or I receive a Microsoft C++ error that shuts the program down when I render a file.
I'm using CS4 4.1 with matrox hardware Axio utils 4.1, on an Axio LE, system running in windows XP service pack 3.
For troubleshooting general crashes, this ARTICLE might be of use.
Here are some more TROUBLESHOOTING tips from the PrPro Wiki.
In general terms, crashes are usually related to:
1.) System - more details would be good
2.) Assets - tell us, in great detail about your Assets
3.) Project - I assume that you are doing Matrox Projects, but don't know that for fact. Please give your Project Presets and settings.
