I am also having the same problem with the "please wait.." then it asks to "Press continue." It seems that MediaLab is skipping over my GNAT that works perfectly in Inquisit. I am on a school computer, so I cannot change any pathways on it and I have tried changing the file type to "executable file" instead of "Inquisit session." I am at a loss and this is for my thesis which needs to be up and running by Monday!
