What does expiry of 60 minutes in games downloaded from yahoo, aol or msn etc.?

Question

After playing a downloaded game once. It shows expiry of 60 minutes. After downloading the same game again from the same earlier source, it does not allow me to play again.

What is the reason?

Answer 1

cause it's a free trial version that last for only 60 min if you want to play it again for free try downloading it from a different place - then you'll have another 60 min but to get the full game and unlimited game play you have to buy it

Answer 2

the program is a trial program you must purchase it, and it leaves info in your registry so it knows how long you have used it
