For the benefit of others, it is an SH3 data integrity issue, caused by the deletion of save games.
The easiest solution is to, after you have deleted the saves, reopen the career and go to the barracks screen. I *think* that then corrects the data integrity problem. You should be able to then exit SH3 and resume using SH3Cmdr.
If this still fails, then the solution that *will* work will be to play the next patrol sans SH3Cmdr. After you've finished the patrol, you'll be able to resume again using SH3Cmdr.
Rose, or others with this problem, can you pls try my first solution and let me know whether it works?
