What I have done so far: 

 - Generated new Genesis Block 
 - Generated new MerkleRoot 
 - Updated MerkleRoot 
 - Updated Genesis block values
 - Commented out [these lines][1] 
 - Compiled on CentOS 6  
 - Created `altcoin.conf`with 

>     rpcuser=someuser
>     rpcpassword=somepassword

 - lauched `./altcoin` 

at this point all seemed to be OK but... 

 - `./altcoin getinfo` 
 
shows:

    {
        "version" : 60300,
        "protocolversion" : 60001,
        "walletversion" : 60000,
        "balance" : 0,
        "blocks" : 0,
        "connections" : 1,
        "proxy" : "",
        "difficulty" : 1.00000000,
        "testnet" : false,
        "keypoololdest" : 1400530204,
        "keypoolsize" : 104,
        "paytxfee" : 0.00000000,
        "mininput" : 0.00010000,
        "errors" : ""
    }

 - 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

which shows: 

    {
        "blocks" : 0,
        "currentblocksize" : 0,
        "currentblocktx" : 0,
        "difficulty" : 1.00000000,
        "errors" : "",
        "generate" : true,
        "genproclimit" : 4,
        "hashespersec" : 0,
        "networkhashps" : 1.46543,
        "pooledtx" : 0,
        "testnet" : false
    }

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

    Altcoin Network: genesis=0x00000000324a1b505ecd nBitsLimit=0x1d00ffff nBitsInitial=0x1c00ffff nStakeMinAge=604800 nCoinbaseMaturity=500 nModifierInterval=21600

    nBestHeight = -1
    setKeyPool.size() = 101
    mapWallet.size() = 0
    mapAddressBook.size() = 1

 - uncommented [these lines][1] 
 - lauched `./altcoin`

and the same error over and over again... I am cracking my head already a while.... 

can one, please point me the right direction. thanks
