When attempting to get security access, the TIS gives me an error code.I looked into it and it seems that I am using a rs232 adaptor that is not compatible(Insignia NS-PU99501). I have java 6 running and it seems to work well until the start screen will read down load mode, then just loop back to the Saab screen. I have already pulled the trigger on a Tripp-Lite USB adaptor, but in the mean time is there anything else I should look into? Running on a windows 7 with java 6. Thanks for any help.
