"Error! Check activation'

[rafaelp95669126]

I´m trying to open my e-book into ADE (4.0). My computer S.O is windows 7. I don´t know how to figure this out. Please help me!

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 !!

Thanks for you help! But i´ve already tried this solution but it didin´t work. When i try to deauthorize, the ADE shows the following message: "Unable to remove the authorization. Please try again later." I tried it yesterday and right now, but it didin´t work. What to do next?

Hello everybody! I fixed the issued with a workaround:

1 - Uninstall 4.0 ADE version;

2- Install the 3.0 ADE version;

3 - Deactivate the device successfully;

4 - Install 4.0 ADE again;

5 - Reauthorize the device and it´s done.

It worked for me!

This worked for me too. It is a great solution. Thank you.

I tried that but the 3.0 version does not give me an option to deauthorize my computer.  Any other suggestions?

Try control-shift-D to get the option...worked for me, and I was having the same issues.
