I'm usuing pSX VERSION 1.10 as that's the only one that'll work for me, for some reason.
I tried downloading v 1.11 and gor an error message, then tried to see if the new 1.12 would work, and got the same one.

is it something that I can fix? if you need to know my OS it's Windows Media Center with SP2.
