While it is detailed, it's not as advanced as it looks. It uses no meshes that aren't included in the game and all the custom textures are low resolution. I even compensated the detail by making the map only half the default size. You guys are just putting it into your exports folder right? That should be all you need to do.
I can run some more tests to make sure the files aren't damaged on my host, but all my machines are high end or I built them personally, so if it is a problem with lower end computer parts there isn't much I can do to troubleshoot it on my end. Sorry.
