Hi All I never said this but should have: Do not run the DXBUpdater while DXBase is running. Windows will only let you open a file in one program at a time and if the refdata.mdb file you want to change is in use by DXBase, it will fail trying to open it! 73 Neal Campbell Abroham Neal Software www.abrohamnealsoftware.com (540) 645 5394
