LCD Touchscreen from SAINSMART

I have purchased a SAINSMART LCD Touchscreen including a Arduino-Mega from SAINSMART.

It came with a calibration sketch loaded and this works. So the hardware looks ok

Now I want to install a different sketch but I got errors during the compilation.


I think my IDE environnement has some problems.

My question is who has also a touchscreen from sainsmart and what is your folder libraries and hardware containing?

From where did you download the software? Can you maybe send me your set or URL please?
