Yes, well I think we all feel it shouldn't be so difficult! However, I'm glad to say that something worked today. I decided to start all over again and re-install the plug in.I'm not convinced I did anything different but it seems to have sorted itself.
Thanks to everybody for their support and advice;it kept me going.Now I can get rid of DPP which I never wanted in the first place and do everything in PE7 which is kinda what I paid the money for!
Put it down to experience...the stuff you can't pay for!
Thanks again, guys
