Need some help on returning to play PSO2

[Skize]

So using the AWS+ProxyCap method, I get the 650 error. Unfortunately, I completely forgot which e-mail I registered my current account under... Can someone tell me where I can go on the main site or where ever to find out which e-mail I registered the account to?

Better off using Proxifier instead of ProxyCap. ProxyCap causes more Latency issues on your end than it's even worth (Needs to always be ON, which causes Lag, and in order to switch Blocks. Otherwise, you can't switch unless it's OFF.)
