This problem has occured before, I would:
- Create an application
- Install it and some friends install it
- Change my mind in developing it and delete it, forgetting to uninstall the app.
- "There was an error loading your applications. Please try again later."
I just did the same thing, except this time I remembered to remove it from this account but not my other account, and now "There was an error loading your applications. Please try again later." problem has arisen again.
Edit: Nevermind, apparently it fixes itself after the next hour.
