One common reason for this to happen is that you do not have write  
permission for the defaultFolder. (It's more of a problem on Unix and  
Mac OS X systems.) On startup, the defaultFolder property is always  
set to the folder that contains the Revolution application. Not all  
users on a system will have write access to that folder. Try changing  
the defaultFolder to a folder that you do have write permission for  
(I'm assuming OSX here):

set the defaultFolder to /Users/myusername/Desktop/

Then try it again. Chances are it will work this time. If this  
doesn't fix it, try switching to the multi-line message box and enter:

openFile "myfile.txt"
put the result

Then hit the enter key. If there is an error 'the result' should  
contain information about the error.
