Membership.CreateUser error

When calling "createuser" as follows:

Dim theMem As MembershipUser = Membership.CreateUser(txtUsr.txt, txtPwd.Text)

I get the following error:

System.Configuration.Provider.ProviderException: An exception occurred. Please contact your administrator. ---> System.ArgumentNullException: String reference not set to an instance of a String.

Okay, more info: I have "requiresQuestionAndAnswer="false"" in web.config, but this error seems to be related to the error "InvalidQuestion". So perhaps it's expecting a question/answer even though I've told it not to?

I know that the case is important in web.config - do I have it right?

This error was discussed in http://crlab.com/forums/viewtopic.php?t=6618. This fix will be included in the next MySQLDirect .NET build.
