2.0 Beta 4 Editor won't launch

[The Handwoven Box]

When I open SMBX and click "Create", the launcher closes, my mouse has a little spinning circle for a few moments, and then nothing happens, and the editor does not open. Am I missing some sort of file? Is the app being blocked by a firewall? I can play the actual existing levels just fine, but not the editor.

For anyone curious, this was solved by me putting the SMBX2 folder on my desktop, before I did it was inside another folder that was on my desktop.
