Can't Export Mixdown

When I start Exporting project into wav or mp3 about half way during export I get about 30 pop up winodws of " Microsoft C++ … a program has stopped responding".

tried restarting the system. but it still happens

Sounds like a Windows problem. Is there an update for your graphics card available?

yes there is but that update makes the audio click once in a while

Virus?

ok after more tries, and restarting, it finally exported the project
