I'm having trouble uploading downloads

I am new to this, so pleas bear with me. I've downloaded the NoLimits 2 package, and have several coasters downloaded in the files folder. But every time I click on them it begins to upload the rides, and I keep getting these error messages....

"Welcome to NoLimits 2 v2.0.2.2 (Windows x86_32)
Cannot load file (Invalid file format: unsupported file version)
Cannot load file (Invalid file format: unsupported file version)"

Does anybody know how to adjust this, or guide me in the right direction? Thanks

Have you applied the updates for Nolimits 2?

Yes you need to download the wingrider update most likely, you can do that in game or on nolimitscoaster.com
