Mana Games

I have TE 2013 1.0f and when I win my first tournament in World Tour mode the game crashes saying "The key is not valid". I got the key from a friend. Could that be the problem or is it something else?

Thanks in advance.

Hello,

you cannot get a key from a "friend".
Now is time to buy the game if you like it => https://www.managames.com/tennis/order_en.html .
