help!!我入唔到msn呀~

MSN登入時的錯誤代碼"80048821"，是表示你的帳號或密碼出了問題。這問題的出現，其中一個可能性是在你設定帳號或上一次修改密碼時，勾選了"將密碼設定每隔72天就過期"這個選項，於是72天的期限一到，密碼就無效，需要重新設置。

解決方法1:
i .確認您的認證




瀏覽 MSN 帳號服務網站，然後按一下 [登入]。如果您已使用您的 Windows Live ID 登入，將不會再要求您重新登入。
輸入您用以登入 Messenger 的使用者名稱和密碼，然後按一下 [確定]。
如果您已成功登入，您就會看見 [登出] 按鈕。如果看見錯誤訊息，您的密碼就可能不正確，或是您的帳號已經過期。





ii. 重設已忘記的密碼


按一下 Messenger 登入視窗下方的 [忘記密碼]，再依照螢幕上的指示操作。
SOLUTION2:
Before you start. Did you enter correct Username and Password?
1. The date on your computer needs to be set properly. Double click the clock verify that the time and date are set.
2. If your password information is not saved, verify that you are typing it in with the correct case (uppercase or lowercase).
3. Change your password at http://passport.com to something smaller (under 10-12 characters), then try signing in again.
4. If you use a firewall (like ZoneAlarm, Norton Internet Security etc.), it's possible that Messenger doesn't have the correct rights to access the Internet, especially since you upgraded. You may need to re/add Messenger to the allowed list of programs in your firewall if this is the case.
5. If you disabled your firewall in the past, it still may be blocking Messenger. Try restarting it and see if that helps the situation. You also might try uninstalling an installed firewall, to verify that it isn't causing a problem (even if it is disabled).
6. Clear your IE cache and cookies. Open Internet Explorer, click the Tools menu, then Internet Options, then click the Delete Files button, and when that's complete click the Delete Cookies button.
7. Open Internet Explorer, click the Tools menu, then Internet Options, then Advanced tab, scroll to the Security section, and verify that "Check for server certificate revocation" is unchecked. Also verify that 'Use SSL 2.0' and Use SSL 3.0' is checked, then click OK.
8. Click Start -> Run -> enter the following:
regsvr32 softpub.dll
regsvr32 wintrust.dll
regsvr32 initpki.dll

應該係佢在網出左問題,等下就得
