The issue with Paypal has been resolved now. The transactions should go through successfully.
Due to some technical glitch, the payments made via Paypal are currently not getting added automatically. We are currently working on the issue and will update this thread with details at the earliest.
In the meantime, you can transact using the alternate payment methods available in your control panel. To know the alternate mode of payment click on My Billing->Addfunds.
