KIDCHAMELEON'S PROFILE

Hey I ran into *almost* the exact same error, but I believe my first number was 00000513 instead of 00000518. Anyways, thanks to this thread I figured out where my missing resources were. There were some files I stored in the folder with RPG Maker 2003 with my old RPG Maker. In my steam version I placed those files with the folder RPG Maker 2003 and then the battle tab instantly loaded. I'm thinking that the resources were in this directory. Hope this helps! Know, at least, that if the resources are missing somewhere else, that's definitely the issue here!
