I have an AIW 9600 and an AIW 7500...I've given you all the potentially useful info I have learned since having these two cards.
I guess I'm curious why you are fooling with the Cat Control Center...I don't think I've ever needed to do that at all. My drivers install, my remote junk installs, my MCC installs, the drivers install in the proper sequence. I just took a look and I didn't even bother to install the CCC on this system, guess I don't think it's necessary for me. I have installed it in the past but never had a reason to resort to it for anything.
I know how to install the drivers from the CD and the autorun feature of the CD installs all the drivers and the MMC. In case the autorun fails, I know how to install the individual components from their respective folders on the CD.
In short, the CCC is not a critical item. If the drivers work, you are golden.
