Here's a strange thing: I installed AM2 on my new (second-hand) PC and it worked fine. No problems logging on. However I had paid for the pro version, so I upgraded. Now it rejects my log on details "Invalid user name or password". This in nonsense. I know all the details are correct because, apart from the fact that it worked as the free version, all is fine on my laptop, which is also running the pro one. What on earth has happened? Anyone got any ideas?
