When trying to download an ebook I get "Error! Check Activation."

I am using a PC (Windows) and the activation seems all right when checking in the account details.

For this problem, you need to deauthorize and authorize ADE again.

Launch ADE

Help -> Erase authorization.

ADE will be deauhorized.

Now again AUTHORIZE ADE

Help-> authorize computer.

Error will be fixed !!
