My brother brought me a G3 Real Flight from his trip to Houston

I installed it , played it, had fun turned off the computer, next day turned it on and when I double clicked on G3 it didn´t start, What hapenned??? I don´t know but I changed the Interlink from USB port, a small balloon window informed me my Interlink was identified and installed, clicked G3 and off again to practice all day. Then the next day the same problem, changed USB port again and it worked, but now I have run out of USB ports and none will work with the Interlink Controller. They work with everything else including Joysticks and Gamepads i have but G3 will only tell me ther is no Authorized Interlink Controller detected.


What do i do know? I registered the product, checked out Common problems, FAQ and things like that but I see no answer to the problem. Could it be my computer? everything else works fine on all USB ports, I checked through Control Panel and everything seems fine on my PC. Now I am very far away from Houston and I can not return the item for a revision.


I think i might be missing something obvious, please help

Thanks
