This morning I switched the computer where the backend tables are. It is not allowing multiple computers to connect to that backend file.
First when you tried to link to the backend it said something like "That file is already in use"
Now it allows you to link to it but doesn't allow mulitple computers to write on it. It won' allow for new records, etc.
Any idea what's going on? Thanks! The computers are all connected through a Homegroup.
