How can I recover my SongPop 2 account if I’ve lost access to my email or Facebook account?

Hi,
I’ve been an avid player of SongPop 2, but I recently lost access to the email or Facebook account linked to my game. As a result, I can’t log into my account and retrieve my progress, purchased items, or in-game achievements. I’m concerned about losing all the time and effort I’ve put into the game.

Could you please guide me on the steps to recover my account? For example:

Is it possible to link my account to a new email or Facebook account?
What information do I need to provide to verify ownership of my account?
Are there any other recovery options available in such situations?
I’d greatly appreciate your assistance in resolving this issue so I can continue enjoying the game. Thank you!
