recently my internet suppliers servers shutdown and there were some major internet issues (could not connect at all etc).. while this happened i fiddled around with some buttons to try to make it work.. and today the internet has come back on.. however now i cannot go onto msn (it comes up with a message saying im not connected to the internet, even though im visiting webpages, as fast as i used to).. and also some forms on websites do not work. i cannot use myspace pictures upload as nothing appears when i add a photo.. and i cannot use websites such as onlinepoker66 now.. just small things like that..... confusing i know but its the best way i can explain it... i dont know if it could be because of something ive changed in system preferences.. but somethings changed since the internet went down and it sucks 
note: i can still use other instant messaging programs such as meebo.. just not msn
