Elements 13 won't load w/out activation code

[Dave224145047ruz]

Well, after owning this program since 2015, it won't load w/out an activation code. Can't find my code, and I didn't have a problem until this week. But yet the program start up wants me to upgrade. Pretty fishy if you ask me. Help anyone?

If you have PSE installed on one machine and then want to put it on another m/c, you have to uninstall it from the first m/c then go ahead on the second.

That is not required.

You can install on multiple computers at the same time. Only two can be activated for use at the same time. Only one can be used at any given time.
