MSN messenger for an old ME windows system?

Question

my PC is refusing the new MSN messenger 7.0 and i can't find any earlier versions ... the one i have now is 6.2 and it won't start ... it keeps telling me that i need to update it ...
is there a version that will run on my PC as it is now, or do i need to get the wole PC serviced (it's a back-up PC, just one at my other home where i go for holidays- so i'm not always using it - but it would be good if i could keep up with all my conacts)
i am not sure which version of explorer i am running ...
help please ??
