Good evening micromos and welcome back
Let's try changing some of the settings for some reason they seem like they are getting changed.
1..Open a new document and select Format > Font.
2..Select a new font and size in the Font dialog box, and then click Default. Word will ask you if you want these changes to apply to all new documents using the "Normal template" (normal.dot).
3..Click Yes to make the changes permanent. The change will apply to Word's Normal/default style and to all styles based on Normal.
4..To change Word's default page margins, select File > Page Setup. The first tab should be Margins, make your changes to the margins here, and then click Default.
5..Click Yes when Word asks you to confirm the changes. This warning will look exactly like the one shown above.
Note:You can also change other settings affecting page layout (including paper orientation and line numbering) in the same dialog box.
Hope this helps. Doing the above changes should put all future word doc's back to factory settings and from there you can make what minor changes you want.
