Street Fighter II DOS Trouble

PROBLEM SOLVED

Hello there. I would need help about the DOS version of Street Fighter 2. I have 2 problem

1. I can hear only sound and no music (even if i click on ''SF2'' located on the floppy disk drive).

2. When I click on ''Game Start'' the game is asking me something like this

'' Please enter word (random number) on page (random number) line (random number)''

I do not understand why it does this (The instruction manual is garbage)

I have the Original game, 3 1/2 Floppy Disk

Thanks in Advance
