How to add a world

So I recently downloaded no limits 2 and wanted to download a world, so I made an account here and when I downloaded the world I couldn't add the world. I also downloaded the game from the no limits website

Maps can be loaded from any directory using the buttons listed in the pop-out window when you click Play. It's arranged in much the same way as the standard Windows file loader.

Important things to note are:

• NoLimits 2 can only open .nl2park, .nl2pkg or .nltrack files. It cannot open ZIP files.
• The "Home" button redirects to Documents\com.nolimitscoaster.nolimits2
• The "Library" button redirects to the internal parks.

For future reference, here's a link to the NL2 Ask Thread. Small Qs like this ought to go there.

Thank you
