Exporting mainback from .bmp to .stp

[RD03GrapDesign]

Hello,
I've been having some difficulty on exporting my mainback to .stp to use it for NR2003, but WinMip2 for some reason isn't loading images! I've tried everything, and pretty much quit on trying to fix it. Will someone be kind enough to give me a .stp file of it?

Thank you!

Use this, works far better. It's a mainback maker.
