Hello, yesterday i changed my email address for my account after activating LaunchPad. Now i can't use my Simulator to compile my app. Because the login name is stuck with my old Email address. I tried deauthorising but it didn't work. Any idea how to change the login email at Corona simulator?

Having same problem, any ideas?

I am not using the latest corona build, so i am not really sure if this issue has been address. But my current work around is to revert the email address back to what i used before.

I did the same thing. I'm using the current stable release and it's still an issue. I put in a support request, I'll post here when I hear back.

Here is the response I got, I followed the procedure and it worked for me:
1) Exit Corona
2) Remove two files in your ~/Library/Preferences/ folder:
com.anscamobile.ratatouille.plist
com.anscamobile.Corona_Simulator.plist
3) Start Corona SDK and reauthorize
(For future reference, to change the email associated with your account, first deauthorize from within Corona, then log into the website and change your information. The next time you log into Corona you will be asked to log in again to reauthorize.)

Works perfectly. Thanks!
