Hello klem1 and welcome in our forum.
Thanks for your request.
First of all, please update your max2play. Reboot the System and if the file system has not been expanded, please do it now. Reboot the system again.
Then try it again, please. if it doesn’t run, use the option – Compile latest version from sources.
Normally you only need to install the touch display plugin for the 7″ touchscreen. The joggler skin is already preconfigured.
