Its been a long time since I played in DOS.. To open a DOS box I run cmd.ex from the run prompt.. ? Then typing in your MarineAquarium3.scr /p65552 and hit enter.. nothing happens (except getting a new C:\documents and settings\ralph listing). Am I doing it wrong?
Do you have the SS in a different folder other then "C:\Windows\System32\MarineAquarium3.scr" ? Maybe it's named differently than my example shows. Wherever it is add the full path to the name. Sounds like it's not finding the SS
