I upgrade my PC from Windows 8 to 10. I haven’t used EZ drummer for a very long time but when I tried to open it today, it gives me a screen asking for information to authorize it even though I had done so when I first bought it. I get an “invalid serial number” message. I have tried upper and lower case letters, double checked to make sure all characters are correct, tried both using and omitting the dashes, but nothing works. Version is 1.3.0. Help!!!
