Thanks Colin.
I Googled as you suggested but most sites have changed to version 8. I then did system restore to the date before I installed version 8 but although the 7.5 icon appears on my desktop, it won't open. I then tried to deinstall 7.5 but it won't let me!
I think they are going to lose a lot of customers the way this is going because even if I did consider paying, I wouldn't because I don't have confidence in it.
