Hi again and again!!!

When I enabled Teatimer some of the problems came back, so i followed again ur instructions and it disappeared finally, so how am I going to enable Teatimer without getting into troubles again? Teatimer asked me about some changes in values wich I couldn't understand so I pressed the deny change button, that's how i got into troubles agin.

As for the internet explorer problem; I reinstalled it and I downloaded Java for my PC but the problem persists, please help me out , because there are some pages that i can't access like the hotmail page and so on.
I tried for so many hours to fix this but it was invain,,,, no one can help me but u great Shaba... please help
