I am trying to use OPENROWSET to connect to my Access database, but I keep getting the following error:

OLE DB provider 'Microsoft.Jet.OLEDB.4.0' reported an error.
[OLE/DB provider returned message: The Microsoft Jet database engine cannot open the file 'X:\Setup\Database\KDB_X2.mdb'. It is already opened exclusively by another user, or you need permission to view its data.]
OLE DB error trace [OLE/DB Provider 'Microsoft.Jet.OLEDB.4.0' IDBInitialize::Initialize returned 0x80004005: ].

I have checked the database, it is not in use, and there is no password set on the database that would prevent me from getting access to it. Any ideas? Here's the syntax I'm using:

FROM OpenRowset('Microsoft.Jet.OLEDB.4.0',
'X:\Setup\Database\KDB_X2.mdb';'Admin';'', subPSEL_PList))
