I finally manged to fix the problem with Ezdrummer not authorizing every time I used or asking you to authorize it every time you use it n in windows 8 or 8.1. (When you are using it with Magix samplitude studio)
Here is the problem: It is your User control.
How to fix this:
Press Win [Windows key] + R on your keyboard.
type regedit. press enter.
locate the following:
HKEY_LOCAL_MACHINE SOFTWARE> Microsoft> Windows >CurrentVersion> Policies> System
Then Find this Key; EnableLUA, Double Click on it and change the Value data from 1 to 0."
Restart your pc. Test Ezdrummer: authorize restart Music studio test again to see if it worked.
