post error line 609 fix

Database: 57meg Access 2000

Using conversion tool to go to from 6 to 7, and no matter how many different methods i was consistently getting the "unable to post - duplicate field entry - lin 609" error which i have seen a couple of other people getting on these forums.

The original DB file works fine before the transfer on V6.

i tried:

1) convert, test *got the error

2) convert, compress & repair, test *got the error

3) compress & repair, convert, compress & repair, test *works great!
