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!

Not free

It's scamming you making you to think it's free to get and 'use' but you can basically do nothing unless you pay like $130/year. You get one month free trial but if you don't cancel it in right time... Unless you just need it for a day and have time to set up everything for that free trial, don't even bother downloading it. I just wasted my time.

Not as advertised

I downloaded it and tried to open a project I already created only to be thrown a lengthy error. Tried another with the same result. Tried a blank *.mpp file and got the same result. I think I’ll just quit using it after trying it for 20 minutes.
