"Payment Denied"???

<p>My son is trying to submit his common app payment to UVa and when we put the credit card info in, I get the message that the payment is denied. We have no problems with our credit card, limits, etc and in fact, I used this card a couple of times in the past 24 hours with no hitches. Thinking it might be a glitch with this Visa card, I switched to my Amex card (also no problems re: limits, payments are up to date, etc) but also got denied.
Anyone else having issues with this? I'll try again in a little while, but wondering if there was anything I could do in the meantime. Or to find out if anyone else is having the same issues?
Thanks!</p>

<p>The payment gateway vendor had a glitch - just try again - it will go through.</p>

<p>Thanks! We waited a few hours and it did eventually go through.
