Gw1 account.
Just to make sure, are you using email and password. Sometime people try to use Display name (BoCsa) instead of email.
yes ofc. i use my email
Well, the 2 linked accounts do have the same login. So if you are using the same login and not making a typo then you will need to contact support. Top of page-support, then top of page-submit a request.
Hiya. I had a problem similar to yours less than a year ago. I wanted to pop in on my original Guild Wars account after not touching it for eons (I think 3+ years?), even though I linked it to my GW2 account the day I bought GW2.
The way I was helped was I sent an email to customer support from the original Guild Wars’ website. I didn’t know my password since the last time I played was waaay too long ago, so I gave them some of my information and they reset a few things so I could get back in.
Hopefully that helps somehow, and good luck!
