Data Form Wizard -- Errors

[Null]

Hello, I'm having trouble with the Data Form Wizzard.

I can get as far as creating a successfull data connection and selecting the
tables I want, but then when I click Next btn, I get an error that says:
"The following error occurred: 'Value cannot be null. Parameter name: type'

I've tried everything I could think of including service packing VS.NET but
still no luck.

Have you any suggestions for resolving this problem?

Any advice and/or help greatly appreciated.

Thanks in advance.

Cheers!
