An error has occurred when activating this view Graphic is disposed

I get this error after i have installed it? Pls help i see the iphone 5 assets in the left panel but i don't even know how to use the images.

Make sure that you're using the latest version of WireframeSketcher from our website. Let me know if this works for you.

If you still see this error then email me your log file (see support section on how to report bugs) and I'll take a deeper look.
