Error getting License. License Server Communication Problem: E_LIC_ALREADY_FULFILLED_BY_ANOTHER_USER

[Reena0D4D]

Can someone please help me resolve this issue. I bought a e-book from Lexis and they recommended this app. I downloaded ADE but the ACSM link was not opening so I deleted and reinstalled the ADE app. Now I'm getting this message-

Error getting License. License Server Communication Problem:

E_LIC_ALREADY_FULFILLED_BY_ANOTHER_USER

How do I fix this?? Erasure did not help either. Reinstalling does not help, and there's no contact phone no. that can help me. Why have this app if there is no one who can troubleshoot this??
