Order Printer Pro: PDF Invoice

We use this app on both of our websites. We wanted to make some changes to the Invoice and Packing Slip on our new website (www.justgadening.com) but the app wasn't allowing us to do it. Contacted the Developers who answered almost immediately. They suggested we either cleared the cache or used a different browser, which we did. All working fine now. Excellent Customer Service, couldn't fault it!
