FWIW, I also just placed a Poser 6 upgrade order and it went through first time, no problem. Here's some tips for using the CL/DR store based on my prior experiences: * Enable cookies in your browser * If you get an error message during your order, wait 24 hours to retry * While waiting to retry, delete any cookies for www.digitalriver and shop.digitalriver so you start again with a clean slate * If you're claiming the $50 rebate, the customer service person told me to click the link in the rebate notification email. Don't paste it into your browser or try to go to the store directly and type in the rebate code. Apparently the email has some hidden HTML that authorizes the rebate, even though you still have to type in the rebate code. (This screwed me up the first time I used the store, resulting in a 24-hour wait...) * Don't worry about the warnings that you only get one try to use a rebate code. If you mess up, wait 24 hours and try again. The code is only used up once the order goes through successfully. * If your credit card uses your middle initial or middle name, be sure to include it in the "First name" field when they ask for your address. Otherwise your card may not validate and you'll have to retry in 24 hours. (This happened to me when I retried my first order -- another 24-hour wait). * For upgrades, be sure to include the "XF" at the start of your serial number. As noted previously, the "XF" prefix does not appear in Poser 4's About screen. (This one I got right :-)
