@ DoctorDraca:
This worked perfectly, my Computer doesn't block it anymore. Thank you for this great help so far ^^<3
BUT now there is a new Problem : Jtablet says that it's not installed. It is. I reinstalled it multiple times but my System doesn't find it anymore! What should i do now? It also says i should update to Java 1.6 and that i run with Java 1.4 but that's not true. i have updated to Java 1.6, 1.7 and Java 1.8 (Alpha Version for Programmer) now and it still says i have Java 1.4 and jtablet could not be found. ;A;
