ACCOUNT - MISSING ORDER, HAVE ORDER NUMBER CANT FIND ORDER

Hi Adobe,

I ordered LightRoom4 for my daughter (I have the order number) and her processor was too old to handle the mac software updates necessary to run LR4, so she just bought a new computer and would like to install it on her new computer. Previously, she downloaded it and was getting an error message telling her she couldn't open the installer program to install/run the software. Now that she has an up-to-date computer, we'd like to install the purchased product we haven't yet been able to use but it isn't showing up in my order history or downloads anymore. PLEASE HELP. (I tried calling but was less than impressed with the automated phone service that doesn't have options for download/order/account help! Not a happy customer.)
