Adobe Font Activation

I have been recently using adobe fonts. I have been through a large number of fonts finally to find the ones I would like to use in my work. I have activated all of the fonts and they have been working fine until last night. The fonts became unactive and when I tried to reactivate them an error message would present itself. 

I am able to activate other fonts but the ones I had used remain in a state of error everytime I try to activate them. I am concerned that if I change the font and use another font that this issue will appear again.

Has anyone had this issue or has any advice?
