on that line the exceptions comes in
MembershipUser aspnetUser = base.GetUser(username, userIsOnline);
and the actual exception is
The 'PulsionTechnology.CAMAN.Web.CAMANSqlMembershipProvider' requires a database schema compatible with schema version '1'. However, the current database schema is not compatible with this version. You may need to either install a compatible schema with aspnet_regsql.exe (available in the framework installation directory), or upgrade the provider to a newer version.
Can any one help me
