I've just done a fresh install of Win8.1 and whenever I download a file with IE11, it seems there's at least a 50/50 chance that it will say something like "the file is missing or corrupted. Retry?". Clicking Retry and it always then downloads OK but it's rather annoying and I've never had this problem on any Win7 system I've used. Anyone got any ideas? I'm using an Asus Z97-A board with the TurboLAN software from their website, so I wonder if that, or some setting for the Intel NIC could be the issue, although I'd be surprised if the default settings cause this. There was also the Intel LAN package of drivers/apps from the website which I installed but I think that's it as far as the NIC is concerned.
