How strange... sent it two days ago!
Anyway, I've attached it here... hopefully this will give me a little more info on the problems you're experiencing.
Once you've copied this into your main PF3 folder please remove the NoToolTips=1 option from your INI file or set it to NoToolTips=0, then recreate the problem of loading a bad flight plan, entering the FP adjustments page and hitting the Quick Entry option. Please let me know the exact error message received (if any)
Once you've done this test if you set the NoToolTips back to '1' again you will be able to load and use any flight plan again as you can with your current interim version.
