Visual Studio 2008 - Firebird DDEX

Hi, Ive installed the Firebird client ok, and proved via some code that Visual Studio can access and extract via query some data from a firebird table. However, I want to be able to add a data connection via the server explorer (and thereby using the built in data aware components).

I've gone through the tricky DDEX "install".

and In the registry file, FirebirdDDEXProviderPackageLess32.reg, searched and replaced all occurrences of "8.0" with "9.0".

When I come to add a Data connection, I can Select "Firebird data source", and data provider as ".NET Framework Data Provider for Firdbird".

After pressing continue, I can set the Connectionstring, which I set to

Server=192.168.0.16;User=XXXXXX;Password=XXXXXXX;Database=/db/dp.fdb

I can Test the connection which brings up Ok, but as soon as I try and "Ok" from this screen, I get an error

"Failure has occured while loading a type"

Anybody else hit this ?
