Whether your project is focused on or high-performance tuning ?
Community discussions from around 2012 confirm that the demo was discontinued. According to veteran members of the Simsonforum (a key community hub for Simson enthusiasts), the demo version was abandoned because it was old and didn't reflect the latest state of the software. The last update to the demo was roughly from before the project was revamped for its full launch. The final piece of official news about the demo was an announcement that a screencast would be made instead, providing a video walkthrough of the software for those who just wanted to see it in action.
