Adobe non-Cloud Based Applications Will Not Stay Licensed

Question

Hi All - been banging my head against the wall on this problem for days.  5 hours with Adobe Chat support has made the problem much worse.  I have InDesign CS6, Photoshop Elements and Premier Elements 12, as well as Acrobat X Standard on my PC.  They are all bought from Adobe on-line, and have worked fine for months.  Suddenly, every few times I launch any of the aforementioned applications the Application Manager pops up and says that the software is in trial mode, and I can either continue in trial mode or enter a serial number.  Entering the number allows the app to run 3-5 times before it again reverts to trial mode and forces me to re-enter (again) the serial number. 
Endless hours with tech support has gone nowhere.  They all focus on the SLCache folder and making it universally accessible, which it is already, and in any case that was never touched before this started,  A few other file deletions they did only made things worse.  The problem was initially only with InDesign, and now it is on all the apps.
One last piece of data - all of these applications are upgrades of previous versions that I had.  I have tried uninstalling and re-installing the apps, and even have gone so far as re-installing the older app and then installing the upgrade app.  Same behavior.
Anyone have any idea what I can do?  This is killing my ability to work.  Thanks.

Thank you 1949live.  It does look like your case is escalated so a member of our support team will be in contact you via e-mail.  You should have received an update on 1/26/15 discussing this escalation.
I did review the case notes and I would concur with the suggestion of removing all installed Adobe Creative applications.  All of the referenced applications utilize the same licensing system.  Only with a complete removal can the SLCache and SLStore folders be safely removed.  I would also recommend the use of the CC Cleaner Tool after removal of all Adobe Creative applications and Adobe Acrobat X Standard.  You can find details on the use of the CC Cleaner Tool at Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6 - http://helpx.adobe.com/creative-suite/kb/cs5-cleaner-tool-installation-problems.html.
If you need a new copy of the retail installation files they are available at Other downloads.  I reviewed the registered software titles under your account and they are all for retail licenses.
It wasn't completely clear from the case notes or your post 1949live.  What occurred on the computer prior to this issue occurring?  Was the security software updated or a new security software title installed?  Was a system restore/migration performed?
