Thankfully my sis still has xp on her laptop so I've hooked that one up instead. The problem is my serial - usb connector has no vista support, my laptop did pick up the new hardware but installed it as a seperate com port to the ones the program wanted to use (please don't ask me to explain further cos I don't know).
Long term I'll need a new connector that has vista support but short term, my receiver is patched with the latest fw so once I've realigned my dish tomorrow we have free Showtime
