DigiIPServ.exe Not Compatible With Vista?

In my evaluations of Vista I’ve tried to store settings and update firmware on various EL devices (EL-32s, EL-2s, UT-16s) with DigiIpServ.exe. It isn’t storing the settings or updating the firmware. I’ve tried running this program with Admin rights and the built in firewall was turned off. Does anyone have any other suggestions or is this something that Digi is aware is broken in Vista and is working on?
