UPDATE 2

• removed all hard checkpoints from kernel.cpp link

• added ( 0, 0x0000000000000000 )

  // Hard checkpoints of stake modifiers to ensure they are deterministic static std::map<int, unsigned int> mapStakeModifierCheckpoints = boost::assign::map_list_of ( 0, 0x0000000000000000 ) // ( 0, 0x0e00670bu ) // ( 19080, 0xad4e4d29u ) // ( 30583, 0xdc7bf136u ) // ( 99999, 0xf555cfd2u ) // (219999, 0x91b7444du ) ;

• recompiled

• removed all the contents of ~/.altcoin/ folder

• added altcoin.conf

• launched ./altcoind

• issued ./altcoind getinfo - output is still the same

• issues ./altcoind setgenerate true 4 -

• debug.log output is the same as previously

• issued ./altcoind stop

• launched ./altcoind

at this point I it failed again with the same error message

AltCoin Network: genesis=0x00000000324a1b505ecd nBitsLimit=0x1d00ffff nBitsInitial=0x1c00ffff nStakeMinAge=604800 nCoinbaseMaturity=500 nModifierInterval=21600
ERROR: CTxDB::LoadBlockIndex() : Failed stake modifier checkpoint height=0, modifier=0x0000000000000000

• ./altcoin getinfo

• so I try to use internal miner to mine first block ./altcoin setgenerate true 8
• while checking progress by ./altcoin getmininginfo i got strange output

At this point, I've issues ./altcoin stop and when I try to launch it again, debug.log shows:

• uncommented these lines
• lauched ./altcoin

• ./altcoind getinfo

• so I try to use internal miner to mine first block ./altcoind setgenerate true 8
• while checking progress by ./altcoind getmininginfo i got strange output

At this point, I've issues ./altcoind stop and when I try to launch it again, debug.log shows:

• uncommented these lines
• lauched ./altcoind

UPDATE1:

• deleted all the content from ~/.altcoin/ except altcoin.conf
• launched ./altcoind
• issued ./altcoind setgenerate true 4

at this point I figured out ./altcoind starts up without complaining about stake modifier though everytime I want to restart I have to delete the contents of ~/.altcoin/ otherwise error pops up.

output of debug.log:

despite it is up and running and both nodes are connected to eachother, outputs of ./altcoind getinfo and ./altcoind getmininginfo are still the same.

What I have done so far:

• Generated new Genesis Block
• Generated new MerkleRoot
• Updated MerkleRoot
• Updated Genesis block values
• Commented out these lines
• Compiled on CentOS 6
• Created altcoin.confwith

rpcuser=someuser
rpcpassword=somepassword

• lauched ./altcoin

at this point all seemed to be OK but... when I try to launch it again, debug.log shows:
