Help Overwriting Wrong Data / Migrating Updated Data?

OK. you all keep suggesting to use my iPhone because the good data is on there, and i keep repeating that i have no trust in 1Password to not screw up this migration / linking my membership account there first because your steps already resulted in me losing my good, up-to-date data on my Mac.

i've asked half a dozen times now with no reply — does the original, good version of the 1password.agilekeychain file help? can i use this file somehow to access my good, up-to-date passwords on my Mac without first messing with my iPhone? because as i mentioned over email, i made a copy of that file BEFORE i signed up for the account membership and tried migration. i assumed my good, pre-online migration data would be in this file. is that not right? is there nothing we can do with this file instead of screwing with my iPhone? because at this point, i'm hugely concerned that trying this with my iPhone is going to result in me losing all my data there too, and then i'll have lost all my passwords and info EVERYWHERE.
