+LON-CAPA does internal encryption of password information submitted from the 
+login screen, but only keeps the decryption information for a day. Simply pull
+up the login screen again. 
+If that does not solve the problem, please wait for 20 minutes, reload 
 the login page, and try again. If after 20 minutes LON-CAPA still gives you 
 the same message, please email the Server Administrator listed on the login 
 page. The Server Administrator can verify your situation and re-enable logins.
