annoying height map crash

[heartsgirl99]

I was putting my map ingame and then it shutdown feralheart and I tried to put the map ingame but it crashed again. I have paint.net and I type catsofnewOrleansterrian (cats-of-new-Orleans) but when I did, it shutdown feralheart. is there a way to fix this?

Is it in greyscale and same size on both sides? Example: 513x513

[heartsgirl99]

yes but i coulden't find the grayscale.

Perhaps the progam your using does not have a grayscale option.

Does anyone use paint.net and found the grayscale option? I'm thinking about getting gimp since I heard that photoshop cost money.
