Minecraft adding orespawn mod into hexxit mod?

I'm not at all great with computers, but I recently downloaded a mod for minecraft called Hexxit
which is great because there are so many things you could do.
Most recently, I've been wanting to add more mods to my hexxit mod
I have followed a video:

(loud video)
And I did just as they said, but while the mod folder for the orespawn is in the hexxit mod folder and I try to open my hexxit (through technic)
It would load the mojang screen, but after that it would show a black screen and not the minecraft home screen.
I was thinking that maybe they're not compatible, but I see people playing with these two mods together.
Could it be that one may be outdated?
when I go into hexxit's options menu on technic It says my "build" is on 1.0.10
and when I play the hexxit minecraft it says I have the 1.5.2 version.
Sorry if this isn't enough information!

Cool mod
