I do not have any specific tips, but I seem to remember that it should not matter if you have problems with seeing the blip page.
I'm sure there is something on either the tapes or the book that says if you can't see the blip page etc try and imagine a large cross from one corner of the book to the other. I have tried this when I first started and indeed I seemed to be successful using this method initially.
I think basically the best thing you can do is try different things but most of all keep at it and don't give up 
If I can remember where the reference is I'll let you know.
