A brief update on this.
I contacted Corel tech support, an 0800 number furtunately, first time on was told to update my Graphics card driver.
On checking found driver to be the most upto date.
Phoned again today to be told the photos must be jpegs to enable the editing tool!
I pointed out that they are jpegs, but she insisted that as I had put them on the pc hard disc they were already compressed by my camera
So I did as advised and opened them again and saved as jpegs in a new folder, the very first one I tried to edit with Painshop Photo X3 pro I got the dreaded 'Paintshop Photo X3 has encountered a problem.
Immediately phoned back, gone home until 0900hrs tomorrow!
OK, I'll submit this via their website,
It must be easier to to hack into the Bank of England
I think I may yet say, buggerit! And get my money back.
