12:51:13 Injection is working!

Thanks so much for that response, it worked!!!
However it caused another problem. Because I was using VirtualBox, it would no longer allow me to install Guest Additions after upgrading the kernel to 4.5, throwing out errors but the main one being "-fstack-protector-strong". After much Googling I discovered this was because of the GCC version. I updated this to 5 and was able to install Guest Additions
Here are the steps for those who may face the same problem:
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-5 g++-5
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-5 60 --slave /usr/bin/g++ g++ /usr/bin/g++-5
The above will leave version 5 configured only. If you wish to have 4.8 (current) as well:
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 50 --slave /usr/bin/g++ g++ /usr/bin/g++-4.8
sudo update-alternatives --config gcc
To remove repo afterwards:
sudo add-apt-repository --remove ppa:ubuntu-toolchain-r/test
Naturally, if you are running BackBox directly and not using VirutalBox, you simply need to upgrade the kernel to fix the injection issue.
