Map Terrain Help

[DekkaDemon]

Okay, so, I've encountered a terrain problem and I'm pretty sure all of you know what it is.
It's that moment when you crash as you enter the terrain name into the map maker.
I've looked around at quite a few posts about this before, and nothing has helped.
And before you ask;
Yes, it is .png
Yes, it is grayscale
Yes, it is 513 x 513
Yes, it is one layer
I've heard this speak of alpha channel though, and I suppose that could be the problem, but what is it and how do I access it? (I use PS CS6)
Any help will be greatly appreciated!

By the looks of it, it's probably the alpha channel. Buuuuut, I have no idea how to get to that in Photoshop ( If you sent it to me I could def check to see if the alpha channel is the problem tho?

I'd rather not send the map terrain to anyone, but thank you for your offer!

Alrighty. You could probably look up a PS tutorial on how to mess with the alpha channel :v

Alright, so I figured out how to check if there's an alpha channel... and there isn't. And the terrain STILL won't load ;-;
