I just registered though I've been reading and learning here for a couple of years. I used to load my puffs on my converted Pansat 2500 using my old pc with Windows ME, after it died I´ve been trying on my other pc with Win XP but it won't get past 5% and says Write failed. I know I'm using the right cable on serial port, that's why I suspect it's my Win version. Any one else having this problem? I have done my share of reading but can't find a thread addressing this issue. If there is a thread could someone link me please. Thanks.
