Just in case you don’t know, you can still use all of the MIDI that came with your Toontrack software despite not being able to audition it first in ezplayer. In cubase, for example, just drag and drop your MIDI files into the Superior Drummer track from their directory and it will play. It lacks the convenience of first auditioning in ezplayer, but the MIDI runs just as well (I’m not sure about mapping though for other drum software).
ezplayer is handy, but its not essential for playing your drum MIDI if you can’t get it to run.
Hope that helps – and sorry if I’m stating the obvious!
