We are trying to upgrade from 3.03.05 to the latest version 3.3.5. When we first run the upgrade we get a warning "Duplicate Portal Users".
We go ahead and "Click here to upgrade DotNetNuke Anyway" and get the message below. Does anybody know what is wrong with this? TIA.

The stack track looks like this:
[SqlException: Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.]
