help..The CopyX is incomplete..Wad problems

I'm using the XWE to try modifie the copy X and turn him on 4 directions instead a 2d side scroller, I made the sprites and all and save the modifications, but...on the wad have the files PLAYA and PLAYa, when I quit the program the PLAYa turns into PLAYA and it conflicts some images causing a problem misunderstanding the moves and the moves that are in the PLAYa are missing and when I try to do them, it crashes the game...Someone can help me??

With Friendly regards

There's an option in the latest XWE beta that turns off autocapitalization. Grab that, and in the options menu, turn it off.

Thanks dark Warrior, really thanks
