I am using: IntelliJ IDEA 11.1.3 (Community edition) and Maven 3.0.4.
The project contains several modules, one of them creates a war-file. When I use \"mvn idea:ide
I was getting the same error on Mac (i.e. "Error Loading Project: Cannot load module") too. This is how mine was fixed.
That made it work for me, hope this helps you too :)
