I bought Sid's Beyond Earth for $59.00 from Walmart about a year ago.  It would not work even with the numbers I was told to put in.  I took the disk out and put it aside until yesterday thinking that surely it will work now.  It keeps asking me for the numbers again.  It would not let me use it again.  I have everything in Sid's Civilization series.  Help me please or ask Sid to refund my money.
