i have played prince of persia warrior within demo
there is no error while playing the demo.
but when i installed prince of persia warrior within(full game)
after doing the crack the game give me a error that the game ended unexpectedly

Buy a working CD.

this happens to many ppl. jus go to the game folder(where u installed the game) go to 'VIDEO' then go to 'CINE' and delete the file 'CINE0100.BIK'. if u want,u can backup the file(recommended) but i guareentee that the above method(of deleting the above mentioned file) will work. cuz i got the same error and this worked for me.

To solve this issue on my system I had to set my firewall to allow all processes while playing the game. Then it started up and ran like a champ.

I am running Zonealarm Pro and I simply enable game mode and set it to "Answer all alerts with Allow".

Hope this helps
