Linux Mint not working on VirtualBox

[spectralspon]

I'm running a computer with Windows 7 64-bit and I'm trying to set up a VirtualBox with Linux Mint. The version I'm trying to use is Linux 15 MATE 32-bit, but whenever I try to start up the virtualbox, it goes through the automatic boot screen, but then doesn't actually boot up and stays on the screen (see attached picture). I unchecked the "Enable VT-x/AMD-V" box, but it still isn't working. The reason I am using the 32-bit software is because whenever I try running the 64-bit version, I cannot uncheck that box, and therefore cannot run the virtualbox since it doesn't work. Is there any way I can try to fix this? It's tough to find help for it since I'm not getting any error messages, but even if I wait over an hour, the virtualbox still stays on that same screen. How should I fix this?
