Why Did I fail to Sign in the VIP Version?

At times, you’ll come up with the Singin Failed error. Now you’ll only need to wait several minutes (up to 10 mins), and then sign in with your email and registration code again.

Note: Using the Forgot Password method to re-sign in the VIP version is easier than manually enter the password.
