All my files on adobe digital editions are gone?

[#1]

I am having problems with my adobe digital editions application. I have uploaded a textbook onto the application before and now everything I have uploaded to it including my other articles is all gone. I had paid for a subscription of this textbook and it should be valid for another 3 months. Could you please help me recover my files?
