I don't know if this is your problem BUT textures must be sized as a power of 2.

32 X 32
16 X 16
2048 X 1024

they don't have to be square, but sides must be a number that is a power of 2 ( for those mathematically challenged: 2 4 8 16 32 64 128 256 512 1024 2048 4096)

Also, you must EXPLICITLY give a texture, if it uses a default (usually the last texture ysed) I have found things get unpredictable and weird.
