MagicPrefs is a free application for OS X which aims to improve the functionality and configuration options of the Apple Magic Mouse, Magic Trackpad and the MacBook glass trackpad. TLDR if it doesn't work anymore thats it, if it still works then its just a matter of time until it won't. Apple is not likely to replace the deprecated Api's nor provide access to the underlying multitouch technology so that's the end of the line for MagicPrefs and similar software. MagicPrefs is more than 5 years old now and is no longer mantained, the functionality it provided was made possible by Api's that are now deprecated and reverse engineered private Apple frameworks.
