extension for Access 2007 database.

[ConKi]

Greeting All,
I am trying the beta version of Access 2007 and realize that when converting Access 97 to Access 2007, the new db in Access 2007 has an extension of .accdb. I rename the db file name to xxxxx.mdb and the VB app fails to recognize it.

Is there any way to convert the xxxx.accdb (Access 2007 beta) to xxxx.mdb so that I can try my app against the Access 2007 db?????

Thank you for your time,

ConKi
