Block 2507106602597677499 is the correct block to be at that height:
http://87.230.14.1/nxt/nxt.cgi?action=1000&blk=2507106602597677499
If your node refuses to accept it, this means you are on a fork. Your base target is probably very high too, another indication of being on the wrong fork.
If it doesn't recover by itself, you will need to delete the nxt_db folder and redownload the blockchain.
I started 0.7.5 fresh. So no files from a previous installation, downloaded the blockchain from scratch. Also sending and receiving money goes without a problem (I even forged a block yesterday evening).
I will try to redownload the blockchain.
Thanks for answering!
Yes, that's strange. I also get mass of these errors on my public node, but I think I'm sure I am not on the fork, comparing public node blocks info with private nodeblocks and blockchain.
