Photoshop Elements - license apparently no longer recognized

[Guest]

I purchased Photoshop Elements 12 in January 2014 and have been using it since then.  Yesterday, it stopped working.  It looks like my license is no longer recognized.  When I start Photoshop, it looks like it is trying to launch a 30-day free trial.

When you ask a question you need to provide some basic information

Mac or Windows, and EXACTLY which version of the operating system?

Recent Mac AND Windows operating systems have been known to cause "odd" problems

Are you using a computer Administrator account with full read/write permission?
