Import the problem CSV file into one of the two working databases.
Immediately export the imported records from FMP to a file.
Try to import the export into the problem database.
If it works, the problem could be an anomalous character, or an OSX version quirk.
There is only 1 database file. It's being shared through Dropbox.
I just open it on whichever computer i'm on, download the 3 csv files via web browser and import.
It's the same OS on all 3 computers, same version of FM.
I even transferred the problem csv file via Dropbox so that i could eliminate any download differences.
I guess it's some hardware thing except for the fact that the first 2 csv files import without problem, it's only the 3rd one that errors. I'm scratching my head trying to figure out what's different about the third file import.
hmmm . . . what's different?
System Preferences -> Language & Text -> Formats
There is one import field that is a timestamp.
Just ensured the prefs match and it works now.
