I'm trying to run my macros and getting message "Microsoft has blocked macros from running because the source of this file is untrusted."

Because the issue appears when you create a new blank document from the Normal.dotm template (that's the default template if you don't specify another template) and the "Security Alert" message identifies Normal.dotm as the untrusted file, that template is most likely the cause of all the trouble.

The first step is to make sure that the folder C:\Users\Rodney\AppData\Roaming\Microsoft\Templates is a trusted location, which it should be by default. In Word, go to File > Options > Trust Center > Trust Center Settings > Trusted Locations and look for a line whose description says "Word default location: User Templates". If that line doesn't exist, click the Add New Location button and enter that path. Then shut down and restart Word, and test whether the problem is fixed.

If there's still a problem, then with Word shut down, go to that folder in Windows Explorer. (The AppData folder and everything under it is hidden, so the quick way to get there is to type in the environment variable %appdata% that automatically expands to the first part up to and including Roaming, and then add the \Microsoft\Templates part.) Single-click the Normal.dotm file and rename it to OldNormal.dotm. (By renaming rather than deleting the file, you can access it later to copy any customizations that you want to keep.) When you next restart Word, the program will create a new Normal.dotm template with only the default properties.
