trouble with internet

[Carla Wood <carla_smith-wood@dot.state.ak.us>]

I ruined my new computer at home last night. We have internet through a 
dial up PTI site. I was on MSN.com and I accidently pushed a video for 
one of the hot news topics and I hurried and hit the close button for 
the window after realizing what it was. This popup screen came on and 
informed me that an application was going to download on my computer and 
it gave me a few options like, 1.)always accept downloads 2.)manually 
accept downloads 3.) block all downloads... etc.. etc... I hit the block 
all downloads and now I cannot get on the internet at all. I ruined it.. 
Do you have any suggestions?
