Returning player. N1NJ4/illuminatus

I remember playing on this server on GC back after official servers went down. Don't have that account info anymore so I made a new one. Been playing PSO since Dreamcast and have played all of the console/handheld games. Someone told me I could get Dolphin to allow me to play online on my phone, and I would love to get it set up.

Only thing stopping me from this is that when I try to manage my hunter's license, it tells me that my username or email and password are bad. All while I'm logged into this account.

Any help would be majorly appreciated. Thank you.
