When loading CC it tells me it can't locate read Boulder 006 even though it's exactly where it's supposed to be and opens fine with an image editor.

Are you loading any mods?
Love the name by the way.

I am loading(a ton of) mods but why would a mod cause a problem with base.rte?

I've never experienced this problem myself, but whenever there is a problem loading one of the default base.rte stuff, this happens to work best:

1. Move all mod .rte's to a backup folder.
2. Unregister Cortex Command.
3. Reinstall Cortex Command.
4. Move mods back in place and reregister.

If you didn't edit the Base.rte, and this problem just suddenly appeared,
then make a new install of CC and put all the mods in it.

If it persists, then you're either doing it wrong, or it's a mod.

Fixed the problem.
