data sets disappear - unspecified error

Well, I don't know what the real answer is...however, this is the manual labor answer. * Delete the project files (.csproj, .csproj.webinfo, & .sln) * recreate the project in the same web folder * add all the .aspx, .xsd files and the web.config and the global.asax * Now, go back into each form with a SQL connector and right-click on each SQL adapter to reset the SQL adapter back to your connector. * Delete the one line definition of your bad data set (...like this one... protected LoanTrak.dsFinanceDoc dsFinanceDoc;) * right-click on the SQL adapter and re-generate the data set and overwrite it when prompted. These were my steps...FYI should anyone else run into the problem William
