When running UCM VIEWER directly from your local device instead of a web server and UCM files are not being loaded and rendered correctly, your web browser has probably disabled access to local files, because it uses a very strict "same origin" policy.
The first possible solution is to serve the UCM VIEWER directory with UCM files using a local web server. It is especially useful if the web browser restricts the access to local files without providing an easy option to override this. For example with Python installed, you can serve the UCM VIEWER directory by executing a single command "python -m SimpleHTTPServer" (from that directory). Then just open "http://0.0.0.0:8000/Ucmv.html" in your web browser to access UCM VIEWER from the local web server. All UCM files selected for loading are going to be automatically loaded from the local web server.
The second possible solution is to find the web browser option for overriding the "same origin" security feature. For example Mozilla Firefox should work if UCM files are in the same directory as UCM VIEWER files, otherwise you may need to set the "security.fileuri.strict_origin_policy" option to "false" in "about:config".
