Hey there Borisdenn...
This is the help page for activation errors. I would check my host file to start off with:
If you run through that page and still can't get up and running, log out of the Creative Cloud, uninstall all Adobe products and run the Creative Cloud Cleaner Tool, being sure to clear up all Adobe software.
Hope this helps!
I applaud your "going legit", though I worry that the "cracked" software might have left bad things on your system that the legitimate software may not be able to remove or work around. It's best never to mess with such software as it often has malware tacked on. I'd consider a complete system reinstallation, myself.
It's bad enough installing legit software nowadays, with previously innocent apps like Irfanview, Winzip — and all those little apps that make life easier — wanting to change your browser home page and add two or three tool bars. I have twice ended up with malware that caused incessant ad pop-ups in IE, and both times with apps sourced from Cnet, and I am talking about the in the two weeks since I did a clean reinstall of my entire system! And I promise you I was careful to the point of paranoia when installing. So the thought of installing torrent sourced pirated software makes me shudder.
The mvps hosts file blocks access to the ability to download software from sites such as cnet. I think that's a coincidence, because what it's really blocking is the ads from running and apparently you can't complete a download at cnet without allowing them to push ads and potentially malware into your system.
I just find other sites that are not so parasitic.
