If you registered PSP4, you may actually be able to upgrade to PSP9. It seems you have to contact Corel directly to "negotiate" upgrade pricing according to their website, although amazon.co.uk lists PSP9 Upgrade for 31.97. (I don't know in what way the upgrade checks if you're allowed to install it, so it may not be wise to buy that without contacting Corel) BTW Amazon UK lists PSP9 full including Photo Album 5 for 69.99. (Full on its own is 89.96????) And if you don't mind buying through one of those private sellers on Amazon you can get PSP8 new from about 9.
