[SOLVED] Getting the error to run vboxdrv setup (kernel non-match) despite successful compile

I got the error that tells me to run "/etc/init.d/vboxdrv setup" because of VB's kernel modules not matching this version of VirtualBox (it's the latest version), so I ran that (with sudo) and it went successfully with all green "done" messages. But I'm still getting this error. I even tried restarting! What can I do to fix this?

Even after installing "kernel-devel", "kernel-source", etc and recompiling, it still doesn't work!
