INSTALL VERSION 10.0.....,THERE ARE PROBLEMS WITH YAHOO MESS 11.

can you get an internet connection?

click start control panel internet options you will see a home page box To Create Page Tabs type each adress on its own line (type in yahoo.com)

check your firewall settings make sure yahoo is allowed

click start type in cmd press enter
you should have a black screen you are in dos mode
type in ipconfig

you should see all of your connection details
type in your default gateway adress into your browser (search engine)

hope this helps you

try after some time or hours.
yahoo server is down

sometimes YM is very busy for connecting people..that is why you are unable to connect but try reconnecting again...it works

be sure your password and username is correct and your internet connection is stable...

Start your troubleshooting with a clean browser
Download 'ccleaner' and use it daily. Run it through a couple of times,using the factory settings and the 'Run Cleaner' control until 0 bytes are seen to be cleaned following a scan
Run the 'Registry' from the left hand toolbar but 'Save' any changes after opting to 'repair' errors.Never make changes to your Registry without saving the information.

On the sign-in page click Messenger > Connection Preferences - make sure there is nothing untoward in the lower 2 boxes - if incorrect make changes using the drop-box options > OK

Copy this Yahoo secure site URL
https://www.yahoo.com/
Open Yahoo Messenger > Tools > Internet Options > Connection tab > LAN settings > Uncheck everything then check 'Automatically detect settings' and 'Use a proxy server' > Advanced > Paste the address in the secure box and type 5050 in the port box > OK
Sign in.
Hope this helps.
