Could not find stored procedure 'dbo.aspnet_CheckSchemaVersion'

Hi,

i want to create users with the control CreateUserWizard, but by only entering the username. That's why i use the property RequireEmail="false".
In the CreateUserWizard1_CreatingUser event, the emailaddress is then programmatically made by adding "@xxx.zz" to the username.
The web.config contains property requiresUniqueEmail="false".


But when running this, i still get the error "Could not find stored procedure 'dbo.aspnet_CheckSchemaVersion'".
How can i avoid that error and create users only with entering the username?

Thanks for help.
Mich
