Why when i try to buy starter pack from shell shock live 2 it's saying these : I have not received all the information from this application to complete the purchase. Your account has not been charged for this purchase, so please try again. If you still see this error, contact the app developer. (I Play On Facebook) (name Silviu12LGE)
You not the first one to complain about it, apparently its bugged, i suggest to do what it says, try again and if same error contact the developer by sending him an Email kyle@shellshocklive2.com. Good luck.
Go to your facebook settings and find payment method. Insert your credit/debit info there, then open SSL2 and buy starter pack and you will not need to input info and should work smoothly c:
