I put MUSE in my desktop for a trial and I want to add it to my Photography CC apps... what will that cost me or how do I go about adding it?
If you have the Photography Plan that stands ion its own. To get other applications you either have to get Single application plans for each or drop all and get a Complete Plan. If you do the math yourself regarding costs you should be able to see when it makes more sense to get the Complete Plan.
