ok,
i there was a few times that mine dropped connection and what i did was
to use the FTclean utility thats in the program files>efilive>V7>drivers folder,
then installed the drivers in the same folder,
then i added both the scan and tune.exe to my firewall and haven`t had a problem since.
i`m not sure witch one fixed this but
i am not losing connection during a session for no reason anymore.
