First, You need to commit your changes to the team server and then click "sync with web modeler" button on the changes tab next to the "commit" button.
@Daniel, still no luck. Looks like the DTM (Desk Top Modeler) is syncing and retrieving information but it just shows the standard home page.
I'll create the project on the WM again but now using a completely different name. I created a few dummy projects in the past using the same name, maybe that is the problem.
Btw: could it be that the free version of mendix doesn't allow syncing between DTM and WM
Cheers!
