#230 illegal grp4 call 5 - space quest 3

[Captn]

Hi.

After setting all the setting (sound, video, mouse etc)
I get illegal grp4 call 5 when I try to launch Space Quest
3. All the others 1,2,4,5 are working fine except 3. I
have tried all the other setting in the setup. Am I doing
something wrong??? How can I solve this. Thanx
