I am having trouble manually importing position files that are emailed from Yellow Brick
i already have boat ids loaded

i get a file that is "expedition.txt" from YB - it is the expedition formatted position file and it looks fine

i get "unable to import boatid file" again - i already have boatid

i think i remember that years ago when i last did this manually, i had to change them to .csv files  - i tried that and i still get the same error message

i'd appreciate any tips on manually importing these files
thanks
