run-time error '3027' can't update

[stan yost]

All of a sudden I'm getting this error message in vb 5.0:
Run- time error '3027' Can't Update Database or object is read-only.
Can anyone help me with this?
Thanks

Kindly pass few more details .
What is the database that you are using and how you are conecting to database.

I am using an access 2000 database which is on my hard drive. I've created the database and a vb 5.0 program for my small home improvements business. I use it to make bids and to keep track of billing and expenses. It worked pretty well ( I'm constantly trying to improve it) until last night when it stopped letting me update, add or delete from the database.
Thanks for responding to my post.
