Hi I have a similar problem with texture as other Blender user BUT the difference is that all the solutions posted here on the website(blender beta) are not solving my issue..
(Picture 1) I build a game in Blender (** built & Works in Blender 2.57 only)** and textures were displaying at first but since 2015 January the engine started to behave strange..
(Picture 2) Each time I load the Game this message pops up "Texface Conversion problem (see error in console)"
(Picture 3) Even after trying the solution you posted... the Game still looks Black in Texture Mode and Total white in Game mode (after presing P)
In the MULTEXTURE Mode the textures appear...see picture below (Picture 4)
**Lastly.. I only use BLender 2.57 because Latest Versions give me more ERRORS* for example Animations stop working during GAME RUN time*
