owner cannot op DB, help!!!!

[Stijn]

Hi,

I've a sucured db on a shared folder and I'am the owner
and user of the db. (there more users ofcourse) All the
security settings are done using the wizard. All this has
been working properly the last month.
Now, since yesteday I cannot open the db anymore while
other users still can. I don't get any message my password
is in correct or whatever, it just completely closes access
Is my workgroupfile (*.mdw) corrupt or something else?
how can I fix this?
help!!!!

thanks for the advice

Stijn
