Don't worry, currently our bot is having some issues due a recent runescape update.
Should be fixed in a couple hours, if not a day.
If you're still occuring the problem afterwards: shoot me a PM!
Update your java and make sure you have JDK installed. download link : http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
Choose the right version for your computer.
Tell me if it worked.
Click on the windows button at the bottom left, at the top right of that his username of his computer should be there.
Click it, there is the OSBot map and in it there is the scripts map.
Tell me if he found it. Also he might try to search in the bar "osbot" ;)
