I have purchased some EOS during crowdsale. Keypair was generated on official site (eos.io) in accordance with instructions. I correctly registered my EOS public key and claimed tokens, in accordance with instructions. All done accurately, my private key is exactly correct (printed on paper, carefully checked with initial copy-paste and with paper). When crowdsale was ended, I tried to use my EOS account (first attempt - december 15). But wallets (Scatter, Greymass EOS voter) says that my private key is invalid! I can only to watch my EOS account with my public key, and all balances are ok. I googled this problem, and found that many people have same bug.

I writed to B1 support, to 15 top block producers, to Greymass and Scatter support, to Larimer's twitter... and no any answer or helpful answer to now.
