@DarkDome141, please attach files to the feedback tracker or upload them to a free file sharing service such as Dropbox rather than pasting their contents to create a wall of text.

Ideally your friend should have submitted the error report. Regardless, have them try verifying the integrity of the game cache.

Have them prepare and upload a troubleshooting report. The whole report should be made available for the developers to download and review.

For issues regarding Arma 3 you can file a troubleshooting report, also via an action available in the option menu in the upper right corner (gear icon)
