Hello,
I checked the e-mail address you used for registering to the forum against the purchase database. There is an entry with this e-mail address, but the purchase did not succeed.
I can’t tell why it failed unfortunately, but I’m almost certain that you were not charged for the failed attempt. You can verify that by checking your Paypal account.
You can either try again using the normal method or contact support |at| vorpx com for an alternative purchase method, which might work better for you.
