Judging from the way you describe your issue, it looks like you hit a glitch in Graphite. It is possible that you experience an empty simulator view if you try to run it right after you have created the project. There is a period of a few seconds after the creation, during which Icenium downloads asynchronously your files locally. If you try to run the simulator then, it will have no files to run yet. After that those files are cached and all operations should work fine.
Any consecutive openings of the same project should also work normally. Did you try opening your project again in Graphite? If not, can you try? If this is not the case and you still have problems using the simulator, please write us back.
We are also working hard on improving the current workflow so that such glitches don't appear, or at least that users are properly informed of what's happening.
