This issue has been resolved.
Descriptive Problem Summary:
After install 1512, I projects with white-space would no longer open correctly. No files or project folders displayed in the tree. Just an External folder.

Numbered Steps to Reproduce Problem:
Install 1512 and open an existing .dme where there is white-space in the dme file name or path. Not sure if it matters where the white-space is.

Remove white-space or revert to previous build.
Lummox JR resolved issue
Rereleasing the Windows build of 513.1512 with this fix, since it's so soon after the update and the Linux build was not affected.
