Hi to all:

im having difficulties to get silk, and my case is like this; normally i use A-cash to buy silk. and now i ended with 4th times invalid attempt error. i only follow the intruction to add in the E - Pin and Serial No. But still each entry i add its Invalid. Why this happen? Also If 5 times invalid my payment will be blocked.
