I've been repeatedly trying for the past several hours to finalize my purchases through PayPal or VISA (up to the warned limit), but I keep getting slapped with "There was an error processing your order" messages each and every time.

Is there something wrong with the purchasing system?

I've sent a ticket through support but as it is near Christmas, I doubt I'll get an answer in the next 10 hours.

Also, Support said I'd see my ticket to support in 5 minutes. It's been about three hours or more, and I still don't see it. >.<

I've made half a dozen different small purchases on the promo in the last few days and one big one. Two were earlier today. Sometimes there's a blip either with a bank or a processor somewhere along the line. Maybe set your alarm for 4-5 hours from now and give it another shot.

Okay, now I definitely know it's only GOG.com having this issue. Just completed purchases on Steam and Impulse a few minutes ago on the same card and through PayPal. They all went through flawlessly.

*sigh* I really wanted the games I lined up. Y_Y

Made a few purchases this morning. Went through fine.

Lucky. I'm still getting the message. :(

Okay, just tried again. At least now my retry limit has reset and I can keep trying for the next hour. :(

Gah. I'm about to give up. More than 12 hours already and no attempt has been successful. Ever. Y_Y
