I removed the module also but its not working
plzzz help me....

Its not the problem with the simulator but your Driver for the USB Simulator has not been installed. Will not be able to comment on more details without more specific details of Operating systems as well as what are the exact screen shot of the error messages.

May be your USB is disabled in the system or not connected internally?

Follow these steps,
remove the module first for your flysky 9ch
install the needed simulator from dvd (for ex: aerofly)
select aerofly in the dongle (there will be a switch)
plug the dongle
plug the other end to transmitter
switch on the transmitter
if you are using win7 the drivers will install automaticaly..

i am using similar simulator for flysky 6ch, works fine and great(bought from satyagupta )

Sorry for hijacking the topic a little...

Can this simulator be used with my spektrum dx6i?
