If you registered the software your serial number will be in your account at the online store on Adobe.com
Or are you trying to license a trial version? The only version currently available for purchase though Adobe is CS6, or a subscription to Creative Cloud.
trying to license CS6 from last year. Had a trial version.
What are my options?
Buy for a small fortune or move to Creative Cloud.
Or you can subscribe to the cloud and get both CC AND CS6. http://www.adobe.com/products/creativecloud.html?promoid=KCHGQ
I opened an account with a subscription to the cloud .
