It would appear that the version of Paint Shop Pro that came with my computer was a trial version, which has just expired. I can still access things I've made and saved, but only in Dell Picture Studio, so I can't edit them or make new ones.
I don't really fancy paying £70 for PSP, but was just starting playing around and making banners in it. Does anyone know of any free software that's comparable with PSP that I can download? If so, please post the URL (or PM me, if that would count as advertising in posts).
Thanks in advance for any help.
