Photoshop kerning problems


I'm having problems with the kerning on my font in Adobe programs. I've attached an image to help explain.

The black text shows how the font's kerning looks in FontLab. The pink overlaid text shows how the font appears in Photoshop CS5 with standard tracking/kerning.

The ligatures are working in Photoshop, and the font appears fine in Illustrator CS5, so I know the features file is working.

Does anyone know what I've done wrong or what is causing this?

Thanks in advance.
