No Layouts?

I've got a group of databases built in FileMaker Pro 5.0v3. I launch them, launch Lasso 3.6.6.2 and then Dreamweaver 3.01. I create a new document and select Lasso Configuration Wizard from the Commands menu. The URL path is http://localhost/lasso/Dreamweaver/, which I believe is correct. I click "Create Snapshot File" and then again in the next dialog. Then I click "Load Snapshot File". I get an error message: "Snapshot Error: Cannot load snapshot file: file:///Applications/Applications/Dreamweaver 3/Configuration/Temp/TMP-1107027544.htm". When I click OK to dismiss the error dialog, I'm presented with the database selector dialog, but there are no databases and in the database menu and no layouts in the layout menu. The Information field says: Snapshot contains 0 data sources. Current selection is a "FileMaker Pro Data Source"."

I open my web browser and go to http://localhost/lasso/dreamweaver/snapshot.lasso. For each database open the page says:

"Processing FMRemoteDataSource "Database"... Please wait...

Warning: "Database" contains no tables or layouts.

Make sure that the data source is properly configured and that appropriate permissions have been granted in Lasso Security."

In FileMaker, each database is open with the master password, Web Companion is on, Instant Web Publishing is off, there is no logging, remote administration is disabled, security uses FileMaker Pro access privileges and the port is set to 591. Each database is set to be shared using Web Companion.

I go to http://localhost/lasso/security/ and click on All Database Settings. It's set to allow users to add, delete and update themselves.

I perform the same operations above in Dreamweaver on another database which seems to be set up the exact same way, and I have success. The only difference I can find is that the other system (which was a tutorial system) doesn't have any passwords. But the password being used on the problem system is the master password, so this shouldn't make a difference, should it? And the Sharing information looks the same (Single User setting, Web Companion checked).

What am I missing?

Thanks,

Chuck
