Can't reset password on Scrypt Pools account

Newbie here. I'm in a rather unique position with regards to my Scrypt Pools password. Tl;dr version, I can't find any way to get my password or reset it, even though I'm able to log in from one machine. Now I'm crying for help/options.

I seem to have found a bug in my password manager. Instead of correctly saving my generated password for the site, it instead saved my 4-digit pin, and that's all I can get to show up in the manager. Yet, when I'm on the login screen for Scrypt Pools, somehow the manager knows to populate the pw field with the correct password I generated. This allows me to login, but only on the machine on which I started the account.

That's where the problem starts. I want to be able to log in on my phone and other machines, so I need to know what the original password is (can't copy/paste from the password field after it's been populated and I haven't found any other way to get at it), or change my password from the Scrypt Pools control panel. Unfortunately, my pw manager doesn't populate the 'Old Password' field in the settings screen, and when I tell it to use the saved password it puts in the 4-digit pin. That means I can't reset the password from the control panel.

I also can't use the "forgot your password" link on the login screen, because it gives me the error message "Unable to send mail to your address". I suspect this is because I used a gmail address, although no indication was given (that I saw anyway) that there would be a problem with particular domains when I created the account.

This leaves me seemingly without any options. I'll be out of town for a couple weeks and need to log in from machines other than the one I used to make the account. Is there a reason the password reset won't work?
