 ## Troubleshooting
 
-* If Reference Extractor doesn't find any items in your Word document, there are several possible causes:
-  * The citations in the Word document might not (or no longer) be [active field codes](https://www.zotero.org/support/kb/word_field_codes).
-  Active field codes have grey shading by default.
-  You can also confirm citations are active by toggling the field codes by pressing <kbd>Alt</kbd>+<kbd>F9</kbd> or <kbd>Option</kbd>+<kbd>F9</kbd> Alt/Option-F9 (or Option-Fn-F9) in Word.
+If Reference Extractor doesn't work or find any items in your Word document, there are several possible causes:
+
+* Make sure your Word document has been saved in the ".docx" format

+* The citations in the Word document might not (or no longer) be [active field codes](https://www.zotero.org/support/kb/word_field_codes).
+  Active field codes have grey shading by default, while inactive citations have white shading and look and behave like regular text.
+  You can also confirm citations are active by toggling the field codes by pressing <kbd>Alt</kbd>+<kbd>F9</kbd> or <kbd>Option</kbd>+<kbd>F9</kbd> in Word.
   After pressing this shortcut, active Zotero and Mendeley field codes will expand and show the embedded citation metadata.
   Toggled Zotero fields start with "ADDIN ZOTERO_ITEM CSL_CITATION", and toggled Mendeley fields start with "ADDIN CSL_CITATION".
-  * The citations in the Word document have been inserted with a different reference manager.
-* For older Word documents with Zotero references, note that Zotero [started](https://github.com/zotero/zotero-word-for-windows-integration/issues/30#issuecomment-285073023) offering embedded metadata in 2012 with Zotero 3.0.
-  For Zotero 3.x and 4.x, extraction is only possible if the option "Store references in document" was checked in the Zotero document preferences.
