First, sign out and then back in to Creative Cloud, using the same adobe id used to pay for your subscription,
Then, if you launch any CC 2015 product and the pop up still shows a Trial message window, please see this link for resolution:
I followed your instuctions:
1) deactivated device licence in Team administration web panel
2) Uninstalled all adobe apps using Adobe CC Cleaner tool
3) Created new Adobe CC package using CCP Launcher
4) Installed new package
5) Activated device licence starting Photoshop and controlled that licence has been correctly activated in Team administration panel
All this actions has changed nothing. Every time I start an Adobe App a pop-up window is opened saying that it's a test version and I have some other days before expiry day.
This situation started with the automatic update, last Tuesday April 12, of Adobe CC desktop App. Before it was everything all right so it's obvious that it's an application bug concerning desktop Adobe CC licencing that has to be solved.
