Hi Justis, my name is ***** ***** I'll be happy to help you today!
Are you a subscriber to Adobe's Creative Cloud or did you have an older version of Creative Suite loaded from a disc?
Okay, do you still have your disc? If you don't, do you still have your serial number?
Justis, you still with me?
Okay, you seem to have stepped away from your computer so I'm going to leave some information for you. Please see the following link for details on downloading CS5.5:
You will need your serial number to install the program. If you don't have that, there are instructions on the page to retrieve the serial number from your Adobe account. If you never created an Adobe account and you don't have original disc, then your only option would be to subscribe to Adobe's Creative Cloud, and you'd then be able to download all of the latest versions of Adobe's creative products.
If you have any other questions on this, just let me know. And please remember to use the rating box at the top of the screen to rate the answer at least 3 Stars/OK Service or better so that I receive credit for assisting you.
