Hello,

I'm getting this error message while trying to open my project. I was able to open last night but now getting this message. How can I reopen my project?

The "caused by" section three lines from the bottom is the reason but I don't know enough to help further.

```auto
Caused by: com.inductiveautomation.ignition.common.project.resource.ResourceNamingException: 
Cannot add child 'com.inductiveautomation.perspective/views/framework/header' 
to parent 'com.inductiveautomation.perspective/views/Framework'

```

As a workaround until someone else can help, you could try creating a new project and importing parts of that project one-by-one. I suspect that it might choke in the same way though.
