Whenever I try to run the 'multi-method single season' model on my mac (Mac OS X 10.7.5 - Lion) I get the error message:  "Presence encountered an error.  Check input (.pao) and/or design matrix (.dm) files."  Has anyone run into this issue on a mac and found a way to fix it?  I also run windows on my computer but still couldn't get it to work.  I don't think it's an issue with how I saved the file since I can get it to run on a PC.  Any helpful suggestions let me know!
Thanks
