Let me begin by saying that I am new here. I appreciate any help that you might be able to provide, and I apologize if this is a repeat question. I wasn't quite sure where to post it, because it doesn't seem to be an OS issue. I have been having a great deal of difficulty downloading software from the MS download center, and trying to do so can cause issues with other MS products. For some time I tried to download Windows Live Messenger, but every time the download page was unable to load. I had to resort to a friend downloading the install and sending it to me. I got through that problem and thought all was OK, until recently. I tried to download Windows Desktop Search 3.0 from the download center. To do so I have to certify that I have a valid copy of Windows, which I do. The initial validation page will not load the ActiveX control, so I click for the alternative method, which is to download a program called genuinecheck.exe. But when I click to download genuinecheck.exe, that page is unable to load. Furthermore, if I am running Windows Live Messenger at the time, it briefly loses connectivity with the network and has to re-establish its connection. I have tried to test downloading other software from the download center, and suffered the same results. So you are aware, I am running Windows XP MCE on an HP zd8000 series laptop. I have ZoneAlarm Security Suite v6.5.737.000 running, as well as AdAware's AdWatch. My connection is wireless through a Motorola SBG900 gateway. I am happy to provide any other info that might help solve the problem, because I am currently at a loss. Is it a software tweak? A hardware problem? Malware? Any help you might be able to provide is greatly appreciated. Thank you all for your help.
