First, Word 2007 often has some unseen code included in the text if we copy and paste it directly into an online text editor (like what we have in HubPages). In order to make sure I don't bring some extraneous codes along, I paste the text to NotePad first and then copy and paste it to an online editor.
Second, HubPages do save drafts. Simply do not publish your articles. They will appear in your account but will not be seen/read by others.
Third, are we talking about AdSense? Adsense has some policies against certain contents (porn, promoting the sale of guns, ammo, and fighting knives). It might be best to check out their TOR and policy. Aside from those, HubPages also has it's own TOR and policy for content.
Finally, it's always best to contact the admins/mods if your article is perfectly okay and the ads still does not show.
Thanks and wish you the best.
