-----first use default securom profile in the latest Blindwrite program...

--second have you mounted the image with dtools??? and did u install the game from dtools?? if so then the images u created pass the ISo standard installation test...

---third the error "please insert original instead of using backup.(1000)" is the Securom 7+ copy protection keeping you from playing the game...first makesure the cd rom drives are empty and my computer shows the cd drives without the game icon..make sure to unmount the CC3 image ..restart the comp and run the game..
if the same error comes up then mount the image back into dtools and see wht happens........YASU hides cd devices...sort of like ATIP on manufactured CD-Rs...
