hi Szymon,
I have been able to access my legacy software and SDKs here: https://archive.emotiv.com/personal/download/#
not consistently though… sometimes I get an admin access error, sometimes I don’t… maybe trying a fresh browser or deleting your cookies/history helps?
also, the last time I did manage to get in, I downloaded everything locally (SDKs and keychains) to make sure I don’t run into the same problem again.
Good luck!
Suzanne
