LW did not have a downloadable guide for LW 5. The previous downloadable guide they had was for early LW 4.
The reason they refused to make it downloadable was they said to me, the program goes through so many changes so frequently, meaning one downloadable version might be out of date within months. And LW 5 did go through considerable changes over it's time. And had considerable differences to LW 4 on top of that.

I do definitely need to add & upgrade some 'How to do's' with LW 5. I've been thinking recently about posting advice on general downloading with LW 5. Tips & tools that some people don't realise, also advice about how best to go about things.

Some things in LW 5 were never completed by the developers, and at least for MacOSX there are some remaining bugs. Not sure if these apply to Windows but my guess is at least a couple of them do. Of course these bugs passed across to LPE. I've used both LW 5.5 Pro & LPE in depth.
