hi fellow
just received the xl7,tried to upgrade the new o.s. v1.01 many 
times.but failed.
i can goto the the step of:download request received.
and the midi out indicator of xl7 repeatedly flash,then i pressed 
the "download os file to target" soft button on my pc screen. i 
waited so long but the midi in indicator of xl7 never flashed.and the 
e-loader software still remained and stuck in the status:download 
request received.and the xl7 screen still displayed:searching for 
o.s...._
then i quitted the e-loader,and tried to do the process again,but a 
dialog box showed the following message when i re-open the e-loader:
"this application has unexpectedly quit.invocation of this java 
application has caused an invocation target exception.this 
application will now exit.(lax)"
can anyone help me?
thanks in advance.
