what means error code -1504 and how I can fix it?

[Guest]

I have a Microsoft Acess application which works fine for a couple of years
and now I start receiving a error code and the application is not working
anymore. The error code is -1504 but nothing has been changed or adjust in
the application.
Can someone help me?
Thanks

?accesserror(1504)
Application-defined or object-defined error

The error it shows as a separate table in the application, "manfred"
What I do not understand is why after three years of using the same
application this error show up, because nothing has been changed in the
application at all.
Thanks very much for help
