Tunnelbrick not working on MAC

Using this version of Tunnelbrick: Tunnelblick 3.2.9 (build 2891.3328)  -  OpenVPN 2.2.1

The log file kept getting this error: "/sbin/ifconfig tun0 delete

ifconfig: ioctl (SIOCDIFADDR): Can't assign requested address".  This error was in the log file.  I was able to connect to my OpenVPN EC2 instance using VPN but not able to connect to any of the other instances in my VPC.  

The easiest fix is to download Viscosity and use this client product.
