When I download a theme created with the Theme Builder, the .zip has errors in it when opened with SecureZip. When I open it with Windows Explorer or 7-Zip, they don't report errors, but extracting them shows several files with the same name and gives messages about overriding existing files. I think maybe they should be in separate folders, but I can't say for sure. This is happening with any theme I choose. I attached one of several I've tried.
