Greetings!

I'm experiencing a little problem here, and i hope someone can help me.
I've named 10 bitmaps "+xwall" where x are numbers from zero to nine and added all together into some WAD. The texture animates perfectly in the thumbnail but does not move in the surface at runtime.

The silly about this is that i have the EXACT same WMP file that worked perfectly earlier.
Stopped working since i've updated my gamestudio version (just today, december's 16)
Anything known ?

Thanks in advance!
