thanks for the reply,
and now i have purchased another one,(2 keys in my account)
i can not use same WRobot.exe from the same path cos it always use the same key that i can not even try to select.
so i reinstalled a new one, and use the new one to be filled with my new key.
so basicly there are 2 folder of the same program with different keys.....i think this is a bit lame?
