To do its job, Access makes use of various external program and object
libraries. If you move a database from one machine to another, these
references may be "broken".
When this happens, you need to take steps to let Access repair the
reference(s) ON THE COMPUTER WHERE THE FAILURE IS OCCURING.
Here are MVP Doug Steele's instructions for how to do it:
*** Quote ***
Any time functions that previously worked suddenly don't, the first
thing to suspect is a references problem.
This can be caused by differences in either the location or file version
of certain files between the machine where the application was
developed, and where it's being run (or the file missing completely from
the target machine). Such differences are common when new software is
installed.
On the machine(s) where it's not working, open any code module (or open
the Debug Window, using Ctrl-G, provided you haven't selected the "keep
debug window on top" option). Select Tools | References from the menu
bar. Examine all of the selected references.
If any of the selected references have "MISSING:" in front of them,
unselect them, and back out of the dialog. If you really need the
reference(s) you just unselected (you can tell by doing a Compile All
Modules), go back in and reselect them.
If none have "MISSING:", select an additional reference at random, back
out of the dialog, then go back in and unselect the reference you just
added. If that doesn't solve the problem, try to unselect as many of the
selected references as you can (Access may not let you unselect them
all), back out of the dialog, then go back in and reselect the
references you just unselected. (NOTE: write down what the references
are before you delete them, because they'll be in a different order when
you go back in)

Just so you know: the problem will occur even if the library that
contains the specific function that's failing doesn't have a problem.
