I am experiencing a strange problem. After I uninstalled BioShock, which has been installed from a perfect image, activated and it worked perfectly from the image without the disc in DT 4.35.0308 and YASU 1.6.9040, I am unable to play any SecuROM 7.xx protected game anymore. All games are imaged from my original disc using the new SecuROM profile. The images are to be considered "perfect" as they worked before. It pops up the error "insert original disc instead of backup". I changed the info of my virtual drive (vendor, model...), changed device number. Reinstall game does not help.
