--------EDIT--------
The latest version, version 2.1.0.284, should resolve this issue.
Please update to the latest version by using the Check for Updates option on the Help portion of the Software, or by downloading the latest version from here.
--------EDIT--------
Step #1: Launch the Network Connections menu from the control panel (or type Network Connections in the start search bar and hit enter)

Step #2: Right-Click on the adapter called “Hamachi” and select Properties

Step #3: Select Internet Protocol Version 4 and click Properties

Step #4: Click Advanced

Step #5: Click Edit and change the gateway from 5.0.0.1 to 25.0.0.1 (if this field is empty, still change it to 25.0.0.1)

Once these changes have been applied, Windows may ask whether Hamachi is a Home, Work, or Public Network, or you can manually apply this in the Network and Sharing Center. Select either Home or Work on Windows 7/8, or Private on Vista, and everything should function as usual.
