Emu XL-7 & MP-7 User's Group

Tonite I went home with a Midiman Midisport 2x2 USB interface 
from my store and tried to download into the MP7 this OS 1.18 
which is supposed to open a world of wonders for this machine.
I have a new Mac IBook with OS 9.2. 
I installed the E-loader and followed instructions. There is some 
Midi activity coming from the MP7 into the interface, but nothing 
happens with the E-Loader. All is still. Silent. Stiff like a corpse.
I've read somewhere that I should install Java. Well, in my cd 
there is a MRJ installer that won't install, saying "YOU CAN'T 
INSTALL MRJ ON THIS SYSTEM. EITHER RE-INSTALL THE 
SYSTEM OR UPGRADE TO A NEWER VERSION OF TEC".
Tec? What's Tec? What other monster quest do I have to embark 
on now? 
Anybody has a clue? Im really getting bored.
Don't ask me to use a PC, like somebody said a few days ago. It 
should work with a Mac. It should work always. Please. I am 
tired.
