Hello Tanai,
I downloaded the VistaDB(http://www.vistadb.net/Try/Default.aspx) and tried binding it to latest version of C1DataViewSet but it worked properly at my end. I was able to view all the tables in the sample NorthWind Database of VistaDB and then, create a C1DataView based on it.
Kindly check the attached sample implementing the same and let me know your observations.
The latest version is available at this link: http://prerelease.componentone.com/dotnet20/C1DataExtender/2011-T3/
Regards
