+    Something strange must have happened. You may try the following remedies,
+    in the given order:
+
+    <\enumerate>
+      <item>Try to open <TeXmacs> with the <verbatim|--setup> option:
+
+      <\shell-code>
+        texmacs --setup
+      </shell-code>
+
+      <item>Rename your <verbatim|~/.TeXmacs> directory (you may also delete
+      it, but that will irrevocably destroy all your preferences) and
+      relaunch the editor.
+
+      <item>Try reinstalling <TeXmacs>, preferably the latest version that
+      used to work for you. Old versions can be found at
+      <slink|ftp://ftp.texmacs.org/pub/TeXmacs/tmftp/>
+
+      <item>Submit a bug report, report the issue to one of our mailing
+      lists, or contact the authors.
+    </enumerate>
