Isight - question regarding reading a CAE file

Hi, 

i'm a new Isight user.  I need help reading a CAE for a DOE analysis.  I'm able to read an .inp file and run a DOE successfully, but since I want to change parametric sketch dimensions, I need to read the CAE.  However, i'm having issues with this.  When I run the DOE, it just sits there until I kill the analysis.  

I'll be more than happy to provide more information. 

Please and thank you.
