Jogl, Textures and ATI Radeon

[drdoom]

Hi there,
i am new to Jogl and the Forum, but I have a big problem and I really don't know what I should do.
I am writing a small board game in Java and everything works fine. But now I wanted to use the game on my Notebook (which has an ATI Mobility Radeon X700, and on my PC i have a NVIDIA card).
The problem is, that on my Notebook resized the textures incorrectly. So I updated the graphics driver to the newest Version (Catalyst 7.5). Now the textures are resized correctly, but everything has the same texture.
I have already tried to load everything but that texture, but then everything stays white.
Is there anyone who knows what I can do to get the same result I had on my PC?
