How is this mirror script not working?

Link: http://www.roblox.com/cheatmaster18s-MirrorScript-Free-Version-item?id=285480209

Main script:

mirrorScript = require(138295801)
return mirrorScript

I've tried using this mirror script, and I put everything in the right place, but attempting to use it returns this jumble of errors (includes ones that are not related to the main script but are part of the script's required scripts):

18:04:29.686 - httpGet http://assetgame.roblox.com/asset/?id=138295801&modulePlaceId=95206881 failed. Trying again. Error: HTTP 409 (HTTP/1.1 409 User is not authorized to access Asset.). Elapsed time: 0.122052 18:04:29.802 - Content failed for http://assetgame.roblox.com/asset/?id=138295801&modulePlaceId=95206881 because HTTP 409 (HTTP/1.1 409 User is not authorized to access Asset.) 18:04:29.803 - Content failed because HTTP 409 (HTTP/1.1 409 User is not authorized to access Asset.) 18:04:29.803 - Unable to find module for asset id 18:04:29.803 - Script 'ServerScriptService.MirrorScript', Line 2 18:04:29.803 - Stack End 18:04:29.803 - Requested module experienced an error while loading 18:04:29.804 - Script 'Workspace.Mirror.runMirrorPublic', Line 31 18:04:29.804 - Stack End

I can't tell what exactly is wrong. I asked about this on the forums, but I bumped it too much and everyone began ignoring it, and the creator of the scripts is currently offline.

So what is wrong with this mirror script and what would cause it to work?

P.S. I'm sorry for being such an idiot with my first question.
