We apologize for the inconvenience.

I look at the log, it says this

[2014.05.19-17.26.26:068][  0]LogSlate:Warning: GetFontFace failed to load or process '../../../Engine/Content/Slate/Fonts/Roboto-Black.ttf'

I go on the internets and download Roboto-Black.tff font, and insert it to the corresponding folder.

Now I get this

This happens only on this one project, but this project is very dear to me and I want to recover it somehow. Any help?

Hey zantze -

I am going to need a little bit of information about the project to try to track down a solution for you. Since it is just that one project the problem is probably in the default loading map when you open the editor. Thinking about that map, Can you give me a basic rundown of items in that level (for example: static meshes about 10, matinee actors 5, particle systems 10 etc…) ? Also, are you building a completely custom level or was it built off of one of the templates and if so, which one?

Let me know and I will try to reproduce your issue.

I am excepting this answer for tracking purposes, if the problem has persisted or returns feel free to post again.

Thank You

Eric Ketchum
