I ran through the interactive tutorial for "Build a Photo Album" a month or two ago successfully.
Today I deleted the project it created and tried to step through the same tutorial again.
When I try to "Run -> iPhone" at the end of step 1, the simulator iPhone screen is blank (white).
If I use AppBuilder to run the project on an actual iPhone or Android the result is the same.
What's going on?
I'm on Windows 8.1 and using a Chrome browser.
I've tried using F12 in the simulator to see if I can find an error, but no luck.
Any help would be appreciated!
