[LVL ED] Material is not working...

[Plazmater]

So i got this problem yesterday and i was frustrated.

I created a primitive plane and wanted to give it certain material that is from AAMFP, like floor texture.
However, its not accepting it somehow.
It accepts any texture from ATDD but this one doesnt.

For example, i create a plane for floor and i give it some floor texture from ATTD, then i change my mind and give it texture from AAMFP(.mat file shows when i choose that texture) but when i click back it changes to ATTD texture automatically.
I have my AAMFP texture copied to custom story folder.

It worked before but i dont know what happened.
Any help is much appreciated.
