Client updated to 0.7.5.6

modified the blockchain file structure.
reduce the memory useage.

At the moment many people have problems to get connected to the blockchain properly. The problem is due to a certain block in the blockchain: 630091

After client version had been updated to 0.7.5.6 all clients could only receive data until this block. So the developer team uploaded the previous client version 0.7.0.5 to the darknetspace website again. Using the old version of the client it had been possible to get the blocks after block 630091. So I used this previous version again in order to catch up with the blockchain and it worked!

Since it had been working well, the developers uploaded client version 0.7.5.6 to the website again. In the following I had been using the 0.7.5.6 version of the client and everything worked well.

But now I am facing problems again, because the new client version 0.7.5.6 no longer accepts my wallet file. So I started to rebuild my wallet data file as described below:

How to re-build wallet data file
Wallet consist of two files: wallet data file, that usually called my_wallet.dnc and wallet keys file, that called my_wallet.dnc.keys. Last one is very important, better to keep backup of this file, and if you lost this file youll spend you coins.
Wallet keys file creates only once and then newer updated, its used only for reading, unlike wallet data file, which is used for keeping transactions history and organizing internal database, and updated after ever wallet use. Sometimes, by different reasons, wallet file may be corrupted, this is not critical since you could always re-build your transactions history by re-synchronizing wallet with blockchain.
To re-build wallet data file:

close wallet
rename my_wallet.dnc to my_wallet.dnc.backup
open my_wallet.dnc.keys and wait until re-synchronizing will be finished
When re-synchronizing finished youll see recent transfers history (but you wont see receipens since it was lost with original data file) and now you able to use your wallet.

By doing this you can rebuild your wallet file from scratch! But there is a problem in doing this task at the moment! The old client version 0.7.0.5 is no longer accepted! But actually this old version is needed to get beyond the block 630091! But using the new client version 0.7.5.6 one cannot get beyond block 630091! After starting mining with the client you can create your own blocks after block 630091, but this is not the correct blockchain any more! There should be a way to connect to the correct blockchain! I hope that the developers will take care of this problem! Sometimes only one or two miners are mining on http://dnc.geilidao.com/. But I cannot connect to this mining pool any more!

I have been mining this coin for over one year now, so I know what I am talking about! There are only two exchanges for this coin at the moment, but it has already some decent value! However it is a problem at the moment to send these coins since the blockchain is not working properly at the moment!

The developers will take care of this problem, because they benefit the most of all if things are working properly and the coin price will raise!
