Error message when test playing after trying to make an intro

[Chi-baka]

Fo my game, I'm trying to make an intro where an image with text scrolls past telling a story. However, when I try and test play with the intro, it gives me an error message that says 'File Data/map000.rxdata not found'. If I remove my would-be intro and attempt to test play, it still gives me that error. This is really starting to irk me and I'd appreciate any input. :/

transfer the map to a new game..
Put Ctrl + C from the map list at the left and ctrl + V again in the new project..
