okies, so its probably a simple cd/dvd check as suspected...
i can look at it for you if you want, or attempt to help you make a mini image etc..
alternatively you could load a hex editor and patch file offset 0x1940 (thats 1940 HEX)
with 33 C0 40 C3 (xor eax, eax.. inc eax.. ret).. aka return TRUE;
that might work (no idea, because if i run the launcher here i get prompted to install), i think
the actual exe is the sport.dat or similar.. and the cd/dvd check may not actually be in this
launcher.. but you have all the files so you can test
