Yes, I received a promising reply yesterday. It seems someone tried to access the account, which they mentioned could be due to malware. However, I'm now having trouble with the next step: signing a message with the wallet I used to pay for my Copper membership to prove ownership.
How about this address you once posted in this forum.
BTC address: 1M4iALHHcX48m2cEwfyBGLJttL8cZD1Ef9
Are you able to access it's private key or back-up seed phrase?
I believe if you signed a message from that address and email the team about it, that could put you a set closer to unlocking your account.
