Failed to accept block ...

[vicar]

Hi,
I'm newbie in this world.. I installed NRS 0.72 client on Ubuntu and while block was loading, Ubuntu's terminal shown this message:

Code: [Select]

DEBUG: Failed to accept block 15469367769796613648 at height 56146 received from nxtnode.eu, blacklisting
[2014-02-11 19:41:59.388] DEBUG: Blacklisting nxtnode.eu because of: Duplicate hash of transaction 6120913904145250080


Anyone can help me?

Thank you!
