CDaoException ERROR (Error 340) when accessing txt file

Hello,

I'm trying to import data from a text file in BO XIR2 and get the following error :

CDaoException SCODE_CODE = 340 SCODE_FACILITY = 4 SCODE_SEVERITY = 1 ResultFromScode = 2147746132

I've seen a another for an older version of BO suggesting to re-install microsoft data access but these software is already part of windows XP (it does not let me install any previous version).

All suggestion is welcome.

Thanks.
