well thank you all for your great help.. It's 10:05 and I couldn't wait till tomorrow to check if the program works..
I got (don't ask how

) version1.2.1.2 dated 3/12/2006 part number 763724....
I don't know if that helps anybody but the thing, against all predictions, is that is working with Vista business...believe it or not... may be one of the only things that works in Vista....
Also, I found another option to the DB-9 connector to USB... I bought on Ebay a PCMCIA card with a serial port... the funny thing is that the card cost $4 and the shipping??..... $12... total 16 bucks, and is espoused to take 3 weeks to get here but I got it on week and a half...
well, long story short, everything worked flawless... connected right away and was able to SEE (cant modify anything)
I also found the source of my problem with the two engines labeled as port...
Well sharing my good news, I hope is useful for somebody else...
