1. Do you have create / Read / Write / Delete on the Folder where the MDB
file is in?
2. Try:
Close Access completely / Check the directory where the MDB file is in and
see if you find the file <yourdatabase>.LDB / Delete the LDB file if it
exists and then try opening the database again.
3. The database may be set to open in "shared" mode but you might have
opened it in "Exclusive" mode previously and if you use the MRU, IIRC, you
will open the database in the same mode as you last opened it and it could
be "Exclusive" mode.
Try:
Open Access software by itself / Use the Menu File / Open ... / Use the
Dialog to navigate to your MDB file. Click the DownArrow next to the "Open
???" button. Select just "Open" while you are holding the Shift Key down.
Don't know what else can be wrong if the above doesn't work.
