Now you have the last chance to decrypt your files. Open http://jssestaew3e7ao3q.onion.cab or http://jssestaew3e7ao3q.tor2web.org in your browser. They are public gates to the secret server. If you have problems with gates, use direct connection: 1. Download Tor Browser from http://torproject.org. 2. In the Tor Browser open the http://jssestaew3e7ao3q.onion Note that this server is available via Tor Browser only. Retry in 1 hour if site is not reachable.
