Hey guys, could you please check a file from the installation to see if that has been updated properly?
For windows users this file is located in
C:/ProgramData/Toontrack/EZdrummer/Database/02_@EZDRUMMER_2_MODERN#VINTAGE/midiDB
For MAC users it is located in
Macintosh HD/Library/Application Support/EZDrummer/Database/02_@EZDRUMMER_2_MODERN#VINTAGE/midiDB
If you check properties of this file it should have a size of 485,376 bytes.
If this is not the case you could try renaming the subfolder "Database" to something else, for example "Database2" and then run the updater again.
Let me know how it works!
