drm license

[frustrated]

I am having a problem with the DRM license. I upgrade it and then play audio
books from the library and half way through the book it just stops playing
and says I have to do an upgrade which is the rights. I have spent many
hours trying to do this. I get it to work for a while and then it happens
again. I have gone back and change the name on the drm and reloaded it but
this time that is not working - why is this happening and what can I do to
fix it permanently

Which DRM license? For which product? Upgrade it how? For books from
which library? It stops 1/2 way through which book(s), all of them?
What is the full, exact text of the message about doing an upgrade?

I would tell you to contact the support for your 'DRM license/software',
but you don't say who they are.
