Does not open MPP from email

Opens the sample file nicely, and displays the project plan in a format very similar to MS Project. However, does not open my project from an email. App opens briefly to the splash screen then crashes. Looks to have some nice features, fix the email MPP crash issue and you will have something here!

Finally - MS Project File Viewer

Someone finally came up with a MS Project Viewer that doesn't need to convert the file to something else first. This app can view the original file, which is great for the iPhone!

Nicely done!

Looks like a good up when it works. It however crashes anytime the file is opened as an attachment through a mail. You will have to save it int Dropbox or somewhere else and them try open it again before it works. Menu items are also sluggish in performance.
Would give it a 5 if these two are fixed
