I made a copy from prince T2T i use DVD Decrypter and i do ''ISO'' file.
Also the DVD Descrypter make mds file.I install the prince from this iso file and i use the DT4 to make the installation.I use the mini image (POP The Two Thrones - SF3 Mini Image.mdf) but the prince ask for the serial and after for the cd it's not corect on the cd rom.
