Need help with map painter. :(

[Whitepaw]

OK, im making my completely awesome map. I spend 30 mins making the terrain, then when i go to paint it, i choose the texture i click, press load then i CRASH. If you know why, please tell, cause im utterly baffled.

That sucks, did you save at all?

The texture may not have been the correct size or format. All textures must be in either .jpg or .png form and must be a square with dimensions that are a power of two (16, 32, 64, 128, 256, 512, 1024, and don't go higher, seriously).

All terrain textures must be exactly 256 x 256 jpgs.
