its stopped working! error (0x80004005)

[Mosha]

Hello everyone,
I'm creating a E-commerce site for a project and its stopped working!?!?!?

I've done nothing new to it, i was using it earlier today and it was fine, now every time i go to preview it i get this error
Its freaking me out, this is important to me, and the dealine for hand in is fast approaching, please help!

Error Type:
Microsoft OLE DB Provider for ODBC Drivers (0x80004005)
[Microsoft][ODBC Microsoft Access Driver] The Microsoft Jet database engine cannot open the file '(unknown)'. It is already opened exclusively by another user, or you need permission to view its data.

Just a note, everytime i try to access any ASP page of mine and i get this error, it always refers to a the line where i have....

Con.Open "accessDSN"

Any reason why this does it now, and not b4?
I don't understand the error, its not opened by anyone else, and all the permissions are the same as when it worked!

The only thing i did, is create a Report in access to view some of the data, but since this error occured, i deleted it, but surely a report should not do anything,

HELP

Thanks

Tom

Your access database has been locked by something. First, make sure that nothing running is supposed to have the database open. Then look in the same directory as the .mdb file. There may be a .ldb file in that directory. Delete that file.

Also, make sure that your database has the "Default Open Mode" property set to Shared, not Exclusive. You can find this option in Microsoft Access in the Tools Options dialog.
