Material Edtitor crashes when i enter folders!

Convert the file into a .dds format using Nvidias photoshop plugin, or just hit up google to get one for say The Gimp or whichever image editing tool you're using.

You shouldn't be using .png files for textures, they're mean mean people.

Thank you! but i am using them because of the file size!

98 % of games engines can't use png files for textures. I'm not really sure with HPL but I'm fairly certain that's your problem.
