ODBC Driver v5 Error

We are currently using NAV v5.0 and ODBC Driver v4 with no issues. We decided to install the v5 ODBC driver in order to use DateTime datatype, but we receive this error message (in the error message “TABLENAME” has the actual name of our table):

[Simba][SimbaEngine ODBC Driver]Unable to open table: TABLENAME

[Simba][SimbaEngine ODBC Driver][DRM File Library]General error.

Has anyone experienced this error message before?? I’m not sure why the table would open with one version and not the other.

Thanks in advance for any help.
