Hi Len,
Saved Games are not that large so dial-up would not interfere with sending you a save. Do you have a save just after completing Egypt? If so, you could then go to Easter Island and complete it and then if you wish try Chichen Itza again or ask for my save. I may have a save right after Egypt (not sure). Let me know if you want me to look for one.
Cheers,
Bill
