一打開即時通就出現一個對話方塊 都是英文字
Runtime Error!
Program:C:\Program Files\Yahoo!\Messenge\YPager.exe

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

按下確定後 出現
"0x00405850"指令參考的"0x018f1f74"記憶體 該記憶體不能為"read"請按[確定]終止程式

怎麼辦? 請各位大大幫幫忙
