Hi there! I see you're trying to create a new account on Memo Notepad but getting a message that the email is already taken. Let me help you get this sorted out.

To start, can you confirm if this is the very first time you're trying to create an account with this email? Sometimes, the "email already taken" message means the email address you’re using is already registered in the system.

Here are some steps we can try:

1. Try Logging In: Instead of creating a new account, try logging in with that email and your password. Maybe you already set up an account before and forgot.

2. Reset Password: If you don’t remember the password, use the "Forgot Password" option to reset it. This will help you regain access to the existing account.

3. Check for Typos: Double-check your email spelling when registering to ensure there’s no mistake.

4. Clear Cache or Try Another Browser: Sometimes your browser’s stored cache or cookies can interfere. Since you’re using WebKit on Windows 10, try clearing cache or using a different browser to register.

5. Use a Different Email: If you want to create a completely new account and the current email is taken, try registering with another email address.

If none of this helps and you are sure that this email should not exist in the system or you cannot access the existing account, please let me know. We can then check if there’s an issue with the account database or proceed with further support.

Could you try these and tell me what you find?
