After downloading yahoo messenger 9,it says source file not found

HI.......................

it has errors
Messenger "9" 1st version was in Beta (testing) form. The newest version is not, But it's not working well either. Stick to 8.1 until they work out the Bugs. Including people using 8.1 trying to message ones with 9 or reverse they are having compatibility problems; like text not showing,pictures not showing. It shuts down on Vista users , not allowing people to log in.Web cams do not always work. Many things do not work or are missing that YM 8.1 has. It Seems for Vista users it is so buggy Yahoo is giving up on it and are no longer trying to fix it. http://www.ymessengerblog.com/blog/2008/...
You need to remove version 9 completely 1st to Get version 8 to work.
Use this method: Start,My PC, C drive, open Program files.Next open Yahoo file then Messenger file.Click on UNWISE to Un install messenger 9 completely. Do not just delete yahoo file as this can cause problems with other Yahoo programs.
Download the newest 8.1 here http://download.yahoo.com/dl/msgr8/us/ym...
Your contacts list and messages are stored online and will be there when you return to 8.1 messenger.

Another big problem is with the latest update for Flash Player
Flash player 10 Does have conflicts and is causing things to not load or just crash upon opening..Use the link below for a download of Flash player # 9.0.124.0 . You have to remove the present flash player,add/remove programs in control panel, then download the older version.
http://www.download.com/Adobe-Flash-Play...

Some people are losing signal,things fade out, freezing up or getting disconnected . This can be caused my running low on virtual memory! You can increase your memory by going to start button, settings, control panel, system, advance tab, performance, advance tab, virtual memory, change it, make it 1500 kb or higher, In both boxes, click apply then ok . This applys for all instant messengers,MSN, Yahoo,skype ect.

If none of these work for you then kindly do comment back to me.

Yahoo may just be having server issues if the rest of your internet seems to be running fine.

Try re-downloading later on once they may have solved the issue. Remember there are plenty of other messenger programs compatible with the Yahoo messenger system.

To get away from errors you need to use YM8.1
Messenger "9" 1st version was in Beta (testing) form. The newest version is not, But it's not working well either. Stick to 8.1 until they work out the Bugs. Including people using 8.1 trying to message ones with 9 or reverse they are having compatibility problems; like text not showing,pictures not showing.

Download 8.1 here;
Yahoo 8.1: http://www.soft32.com/download_30.html.....
Use this method: Start,My PC, C drive, open Program files.Next open Yahoo file then Messenger file.Click on UNWISE to Un install messenger 9 completely. Do not just delete yahoo file as this can cause problems with other Yahoo programs.
Your contacts list and messages are stored online and will be there when you return to 8.1 messenger.
Another big problem is with the latest update for Flash Player
Flash player 10 Does have conflicts,and 9's latest update 9.0.124.0 Can have conflicts with Yahoo(very rarely, if you are using it with no problems keep it) and is causing some Yahoo Messenger services to not load.Use the link below for a download of Flash player #9.0.115.0 It should work as it's the latest before 9.0.124.0 . You have to remove the present flash player,add/remove programs in control panel, then download the older version.
