I just did a quick format of the DD disk I was using on the Amiga (not on the PC as I had done earlier) and not the file I downloaded the the main NEWICONS website seems to be fine... Dont know why but maybe the Amiga Quickformat adjusted the disk enough to allow a copy correctly...
Well it tested OK on disk but when I copied to my Amiga it gave me the same error.... Grrr
So I just left it on disk and sent the final to my CF HD... It worked...
