Thank you so much guys for the help.
Got it sorted. It was my virus protection.
Even though I've been using Trend for the last 3 years, it's never caused problems before, I've never had to turn it off when installing biab, ( or any other software) hence didn't occur to me it might be the cause.
Wiser next time round.

So thank you all, ( husband thanks you too, I was driving him nuts , while I was trying to work out what went wrong, haha)


best wishes
