Windows 7 is a pain in the neck. I had all kinds of problems trying to get it to work,mainly driver problems. Although they were installed, Windows kept saying they were'nt,took 3 days to get going. Try every bit of advice given on the forum,it should help,also scroll back through the forum pages because a lot of people have had similar problems and other members have been able to give advice on how to solve these issues.
