Did you try to recalibrate in Freerider after it stopped working? Are you able to control any of the little circles above the OK button on the Calibrate Controller screen?
(The input system for the demo and the full version is exactly the same).
Hmmm that is very strange. Installing the full version shouldn't affect the demo, or vice versa.
If you have already tried all other reasonable approaches, this is what I would do:
- Delete both the demo and the full version from your computer.
- Restart your computer.
- Download the zip file for the full version again (just in case there was some error in the download)
- Unzip the full version, possible to another folder on your hard drive
- Re-connect your transmitter. Make sure you don't have any other joysticks/controllers connected at the same time as that might cause a conflict.
- Try to re-calibrate in Freerider
(As you may know there was an automatic Windows 10 update that rolled out some time ago that broke the USB drivers. I don't think that is the problem on your system though since you were using it without any problems basically just minutes before. I just thought I'd mention it anyway. You can find more information here).
I see, well I'm not a Mac user myself so I'm not very knowledgeable when it comes to MacOS specific stuff.
I would still suggest trying to start from scratch as much as possible, deleting the earlier versions and re-installing the full version.
The first thing I would do, unless you have already done so, is to simply restart the computer and see if that makes a difference.
(One more thing, you could try to go into the save game data of Freerider and see if perhaps something went wrong there. If the data somehow got messed up you might be able to get it working by deleting the old save data. The data is stored at: ~/Library/Preferences/Freerider (or something similar to that) )
