Project saved cannot be reloaded: NullPointerException (#113)

I worked on a project saving periodically my data.

At the end I saved and close the project from the File menu.

apparently everything worked fine but when I tried to load my project back I got the following exception:

System.NullReferenceException: Object reference not set to an instance of an object.

at SoftwareIdeasModeler.ProjectXml.SimXmlReader.Load()

at SoftwareIdeasModeler.ProjectHelper.OpenProject(MainForm mainForm, String filename)

Now I'm not able to open my project anymore!

I kindly ask your help since as you can understand it's really frustrating to loose hours of work, for me and for all the people that could get this issue.

I'm available to send you the project simp file,

thanks in advance for your support.

Superb support!

The patch fixed the problem, the project is now correctly loaded and I didn't loose any diagram element.

Thank you very much indeed.
