I deleted the blocks so it downloads a fresh blocks...lets see what happens.

For anyone wanting to reclaim "coins sent, but still with 0 confirmations", without re-downloading the blockchain...
This should recover unconfirmed sent coins back into the available balance (on windows)...

1. Open the C2.0 wallet.... Help > Debug Window > Console > 'RepairWallet' >> Recovered amount will be displayed in output.
2. Close the C2.0 wallet...
3. Open the c2.0 wallet with "-rescan" parameter *
4. The recovered coins should now be included in the available balance.

* Shortcut Example
"C:\Coin2.0\coin2.0-qt.exe" -rescan

* CMD Example
cd c:\Coin2.0
coin2.0-qt.exe -rescan

What happen already show up in the exchanges account with 'Pending' message, but in wallet stated '0' confirmation. Will this work? Will it mess up entire blockchain becoming double spend?

If you have a transfer 'Pending' for a long time, still with 0 confirmations, this should work fine. That is exactly why I did this myself just now.
The unconfirmed send transaction will stay in your transaction list... so if it does get confirmations, the wallet should update preventing ability to double spend.
