Hmm.
Accordingly to the error message, it's the whole image preloading feature that can't works ; because it don't exist. And accordingly to the only reference google can find regarding this error (that happen to be on this forum,
here), it isn't thrown by RPG Maker itself, but by your browser. Since the fix gave is to start a HTTP server, I assume that this version of RPG Maker rely partly on node.js, and on your browser to cache the different images.
As for the fix, I'm not really sure since you are on Windows. Looks like something is preventing RPG Maker to starts its own mini HTTP server, or to access it. Probably a question of rights or IP filtering rules.
