Unable to reset password?

I have found a couple of older threads on the forum with the same issue, but it doesn't look like any of them have a resolution.

I created an account (not this one, obv) with a gmail account a few months ago. Unfortunately, I have lost the password. I have been trying to reset the password for a week now, and despite multiple attempts I have been unable to access the account. I have requested a new password link using the email I signed up with, and nothing shows up in my inbox. I've, of course, checked my spam folder, and done a general search in my email for H5P with no luck.

I have a project on that account that I would dearly like to recover, so any advice or help would be appreciated! I really don't want to start over and duplicate all of that work....
