Already contains a module

I've just installed Mendix Business Modeller for the first time, and I'm attempting to use the Pizza Mario module as described in the "Deploy in 3 minutes" video. However, it's not working for me. As the video says, I create a new project, and download the Pizza Mario module from the AppStore. At that point, unlike in the video, I'm told that "The project already contains a module named 'MyFirstModule'. Do you want to rename the module you are importing?". If I select “Rename”, then the project will not build because it contains errors. If I select “Cancel”, then the module does not download. Presumably I'm doing something wrong, as I'm told by Mendix that it's working for them. Any ideas? Thanks.

Remove your FirstModule (on the left in the project explorer) before importing the module from the appstore.


What are the errors you get?

I tried importing the same module into a new project and didn't get any new errors.
