Update record with two table

have an Access 2003 database that appears to be very corrupt.
I was having a problem and did a compact and repair on it, and I
lost my network connection during the process. Now when I try
to open it (or access it via DTS, VB, anything I can think of),
I get

"The Microsoft Jet database engine stopped the process because
you and another user are attempting to change the same data at
the same time".

I have rebooted the machine that was accessing it, and no
help. I can't reboot the server now because it's a 24/7 file
server. Is there any way to get this database open? I have
searched and found a bunch of demo programs that will
"uncorrupt" it and show some data (but not save it), so I know
it's possible, but is it possible without buying one of those
programs?
thanks
