Rollback of chain. This update is mandatory as the Lobs chain was attacked. Chain has been rolled back to mitigate the attack.  Please follow the instructions step by step to update the wallet.

Steps:
1. Take backup of wallet (wallet.dat) to somewhere safe
2. Take backup of whole Lobstex folder in Appdata (root) somewhere safe
3. Download 2 files from release - one the wallet file as per OS and second Bootstrap file (bootstrap file has blocks and chainstate folders).
4. After download, Run Qt wallet 2.4 on existing wallet particulars and let it run for 5-10 minutes
5. Close wallet
6. Go to Root folder; C:-User-Username-Roaming-Appdata-Lobstex (on windows) and Application Support-Lobstex(Mac) and replace - blocks and Chainstate folders with Bootstrap files of same name
7. Run Wallet

There is a high probability of wallet being corrupted if steps are not followed.

Masternode script has been updated, please redeploy your masternodes on new protocol.

* Mac Wallets will be updated in 2 days
