[chuck-users] new to chuck having machine.add issues

Hi there! I took the coursera course for chuck programming and all was going well until I go to use machine.add() to make my score and all instruments concurrent. for some reason it reads [C]: no such file or directory I added my files to another computer and the same exact thing occurred. every time I add the shred and Any time I use Machine.add() in any other programs the same thing occurs even though i am using me.dir("/myfile.ck") I can't seem to make any of my files concurrent to one another because its not working. Any help is appreciated greatly!! Thanks! Amy
