Paypal is currently going through emergency inspection. At the moment, transactions cannot be processed through Paypal.
Some of users who use Paypal can have experience that have made payments but did not receive Silk.
We will restore Silk to all users that have made payments but did not receive Silk.
Few days could be spent to restore Silk, and we will be taking care of this matter as soon as possible.
We apologize for the problems this may have caused.
