Is this to change from binary to ascii or from ascii back to binary? If it's the first double clicking the .mdl in kotor tool will extract it straight to ascii format, cutting out the need to use KAurora.
The System.BadImageFormatException class refers to a missing or invalid dll or exe. It might be worth redownloading KAurora and making sure you don't move, delete or rename any of the files from where they extract to.
