FF1 installation problems

[Scorpion13mk2]

Hey there all.

I havent played FF in ages, but I got the hankerin to take on the Great Hunt mod so I decided to reinstall the game.

Im doing a typical install and I keep getting this error about the sound, a cyclic redundancy error. Ive tried to do it a few time and it keeps happening.

I remember havin g this problem way back when, but Ive forgotten how to fix it. 

Could any of you help me?
