Hi Jonathan,
Was your purchase made through the online store or do you have a login to http://service.sap.com/support ?
If the latter, you should be able to go in and retrieve license keys or request new ones as long as you had a maintenance agreement in place.
If through the online store, please visit this link: http://store.businessobjects.com/store/bobjamer/en_US/DisplayCategoryListPage&categoryID=57065700
Thanks,
Kristen
