Need a little help please

[-=Nitr0=-]

hey people....
ok ive used about 6 cd's so far trying to make a working copy of Throne of Darkness. i can do a full install but when i try to run the game it doesnt do anything.....but if i install with the backup and use the original play disc it runs fine. Also the fixed .exe files on the gamecopy site give me a "program too big to fit into memory error" which is bullshit considering 89% of 256mbRAM is free. So anyone else been successful copying this game and if so please let me in on the secret.
Cheers.
