Newbie can't go to Oracle XE Home Page today (but accessed it yesterday)

Question

Hi there,
Yesterday I installed Oracle XE 10g on my PC. I could see the home page and then log into the system.
Today I can't see the homepage anymore:
Internet Explorer cannot display the webpage
Most likely causes:
You are not connected to the Internet.
The website is encountering problems.
There might be a typing error in the address.
What you can try:
Diagnose Connection Problems
More information
This problem can be caused by a variety of issues, including:
Internet connectivity has been lost.
The website is temporarily unavailable.
The Domain Name Server (DNS) is not reachable.
The Domain Name Server (DNS) does not have a listing for the website's domain.
If this is an HTTPS (secure) address, click Tools, click Internet Options, click Advanced, and check to be sure the SSL and TLS protocols are enabled under the security section.
For offline users
You can still view subscribed feeds and some recently viewed webpages.
To view subscribed feeds
Click the Favorites Center button , click Feeds, and then click the feed you want to view.
To view recently visited webpages (might not work on all pages)
Click Tools , and then click Work Offline.
Click the Favorites Center button , click History, and then click the page you want to view.
I'm using:
- Windows XP SP2
- IE 7
- The homepage address is http://127.0.0.1:8080/apex
- THe oracle services that I've identified in my PC are
OracleJobSchedulerXE (Disabled)
OracleMTSRecoveryService (MAnual)
OracleServiceXE (Started / Automatic)
OracleXEClrAgent (Manual)
OracleXETNSListener (Started / Automatic)
I don't have any problems in accessing the internet. Just the Oracle XE pages. I would appreciate if someone gives me some clues of where to investigate and understand what's going on. Any link to a helpful doc is very appreciated.
Thanks in advance,
Miguel
