Word – Can’t edit Microsoft Word template

I think you should be able to remove the no-longer-in-existence template by unloading it. From Load or unload a global template or add-in program on Office's help website:

Unload a global template or add-in

• On the Tools menu, click Templates and Add-Ins.
• Click the Templates tab.
• To unload a template or add-in but leave it in the Global templates and add-ins box, clear the check box next to the name of the item.
• To unload a template or add-in and remove it from the box under Global templates and add-ins, click the item in the box and then click Remove.

and from About loading and unloading global templates and add-in programs:

To conserve memory and increase the speed of Word, it's a good idea to unload templates and add-in programs you don't often use. When you unload a template or add-in that's located in your Startup folder, Word unloads the template for the current Word session but automatically reloads it the next time you start Word. When you unload a template or add-in located in any other folder, it is unavailable until you reload it. To delete a template or add-in from Word, you must remove the template or add-in from the Templates and Add-ins dialog box.

1. Make sure you can see the ruler at the top of the page
2. Click in the ruler to place a tab marker and then drag it over to the right hand side of your page.
3. Now double click on the marker and change the alignment to right.
4. Now when you press TAB while typing on that line, instead of just indenting your text a bit, you can type text aligned to the right of the page.
