Some content could not be loaded?

Hi, I upgraded to Cubase 8 and everything was working for the last month or so, now all of a sudden I am getting this message when I try and open up Cubase… “Some content could not be loaded. Either, licenses are missing or trial licenses have expired”.

What? I haven’t changed anything. Why is this happening? My USB eLicenser is still connected. Please help me.

can someone help me with this? Thanks.
