Just to confirm, you are using Windows, correct?
It really sounds like you're missing some files and/or AE isn't set to allow scripts to write files/access network. Please try re-extracting the JSXBIN file and the GIFsquid folder into your AE/ScriptUI folder and double-check the preference to allow scripts to write files. In your case, the script is choking at the point it should be able to write to C:\programdata
