I am running xp and everytime I download a file it says they are corrupt when I try to run them. I have tried to do this on IE 8 and firefox and it is the same on both. I am using a modem connected to a router and have tried taking the router out and using just the modem and it is still the same. I seem to be able to use small files smaller than about 10MB but sometimes these dont work either. Can some one please help as I do not have a clue what to do.1 person needs an answerI do too
