The college I work for has an enterprise license for Creative Cloud, and when we did the updates last week on two separate computers (one a Windows, one a Mac) After Effects (2015.3) converted to a trial version. We've been using it up until the update and now we have 3 days left on the trial. Our software administrator is pretty much at a loss. Any suggestions? Everything else updated fine.
