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

hi scott
i checked the "show midi device(or whatever...)" on e-loader,it 
showed:
emu systems xl7-mfg id-24 mod id-44013 deviceid-0 revlevel-80764856
(plos).
i think it can detect i hooked the xl7,right?
i tried again,and also select the "extreme" instead of "default 
program" at the preference option.(also,i didn't select anything and 
it's set at default prog. itself when i tried to upgrade the os many 
many times b4).
after i power on the xl7(by pressing home/enter and on/off at once of 
course),the xl showed "searching for os..._ " and the e-loader 
showed "download request received" then i pressed the "download os 
file to target" soft button,and the xl7 red midi in led indicator did 
flash once(just once,less than half sec.)then i again stuck in the 
same situation(xl7 said "searching for os..._ and midi out repeatedly 
flashed" and the e-loader showed "download request received".)
i waited over 15 mins (i think if its in proper process just need 
several seconds to a min ,right?) then exit the e-loader.
then i power off the xl7.re-open the e-loader,the e-loader big logo 
graphics just stuck my pc,i had to do"ctrl/alt/del" to exit from it.
is this a bug of the e-loader too?(sometimes the top left small 
rectangular menu bar just displayed half the graphic horizontally...)
thats all i did,any suggestion?pls help.
the glitches and delay between the patterns are too ugly 
listening,even a non-musician/hobby listener can hear it.
thanks
