G-code Slic3r error: Existing work directory required?

Dear: LMR

Hello guys this is Noah again. Recently I have finished the software on my Prusa I3 where I am following the directions for how to print something and nothing happens when I slice with slic3r. Instead this image appears.

Problem Solved!!!

Dear: LMR

First of all I'd like to say thank you for the help from Yahmez in which I could not have done this without. First of all that error for "Existing work required" was solved. Yahmez told me to fix the directory. I fixed the directory by going @ Config.//Repetier General Setting\\ and I changed it into the Repetier directory. Then I ran into this error.

That is when I just simpley uninstalled the software and reinstalled it. Thank you LMR. Now I will wait untill weekend to fix the z-axis on my prusa from there. My first print is going to be a Boomerang I have designed myself. Thank you and bye!!!
