Twitter credentials error !!

Hi splunkers,

I got the errors in "Twitter for Splunk". http://splunk-base.splunk.com/apps/56296/twitter-for-splunk

And logs show.

07-06-2013 22:15:35.035 +0900 ERROR FrameworkUtils - Incorrect path to script: /.bintwitter_stream.py.  Script must be located inside $SPLUNK_HOME/bin/scripts.
07-06-2013 22:15:35.035 +0900 ERROR ExecProcessor - Ignoring: "/.bintwitter_stream.py"
07-06-2013 22:15:37.626 +0900 ERROR ExecProcessor - message from "python /opt/splunk/etc/apps/twitter2/bin/twitter_stream.py" Could not get Twitter credentials from splunk. Error: No credentials supplied, please complete the Twitter app setup

I also got the same question in community site, but it seems to be unsolved. http://splunk-base.splunk.com/apps/56296/twitter-for-splunk

Please teach me solutions. This is a great app to demonstrate splunk..

Thanks.
