Hi NoraO,
Adding to what Jeff said, if you are on a windows can you please try the following two steps :
1) Right click and run the product as an admin and check if its working as desired or not.
2) Please check permissions on Adobe folder : C:\Program Files (x86)\Common Files\Adobe\SLCache & C:\ProgramData\Adobe\SLStore .
Cheers,
