I have click the 'update' tab in LR3.6 and it advises me that I am up to date.Is LR 4.1 so vastly different that free updates don't apply?
Thanks
To go to LR 4.1 from 3.6, you'll need to purchase an upgrade. They're about $80 US . Whenever the version number before the decimal point changes, it costs money to move on.
You can download a trial version of 4.1, play with it for 30 days, and then decide whether it's worth the price.
Note: you need to be running Windows Vista or Win 7 (or if you have a Mac, Snow Leopard in 64-bit) to run LR 4.x
