I am new to Corona. I currently live in India and this was my first day with the Corona SDK (2013.1076). I went through the installation process very smoothly but on Starting the Simulator, I was asked my registered E-Mail ID and Password. I entered them correctly and Pressed the Enter Key and then a Message Box came with " Unable to Connect to the Server. Please Check your internet Connection". I checked the Internet and It was working super-fast. I tried this many times but still It was the same. Any Help would help! 
Are you going through a proxy server or have a firewall that might not be letting us through?
The same problem “Сould not connect to server. Please Check your internet Connection”. for 3 days already, I can’t build any app. Internet is ok, firewall and antivirus off…
Does the simulator run and you just can’t build? Can you try opening preferences and clicking the Deauthorize and Quit link, reboot and try connecting again?
Thanks, it helped
The firewall and Antivirus is off. It is just that without Logging In, I can’t Use the SDK.
@rishabh.nanawati7, please try removing Corona SDK. Download the latest build (1135), Deauthorize yourself from the preferences pane, reboot, and try connecting again and building. It will prompt you to login again. Make sure to use the same email you registered with.
