Error 650 - no email

[SabZero]

I have upgraded my hardware, and now can't log into the game. I have tried several times to click "resend mail authentication", but I haven't received any emails after a day.

I logged in to my SegaID to check the email address and it still is accepted and it works. Or it should anyway. Also added @gw.sega.jp to my whitelist...

I'm using the Tweaker, and no proxy.

If you don't get the email, but still have access to your previous network card, you can try changing your new MAC address to the old one's. (https://www.online-tech-tips.com/computer-tips/how-to-change-mac-address/)

Thanks, I'll hook my old stuff up tomorrow!

I changed the MAC address, but still get 650 :/

Edit to add: the email worked for registration.

I made a new email account with Gmail and it worked! My previous one was @gmx.net (a german provider)
