Hello b3 community,
i got a problem importing my private keys

Maybe there is anybody, who can help me.
Just decrypted my b3 coins from paper wallet and wanted to import them in b3 V2 wallet.
The wallet says: invalid private key (code -5)
got the private key in the following format: WIF with 51 chars, WIF compressed with 52 chars, hex or B64
As i read, the private key for b3 should start with the letter "P" and should have 52 chars

None of my start with P
Is there any possibility to safe my coins?!
Thanks in advance
