Windows Support Software download stuck

I'm trying to boot camp my Mac Book Air 13' 2011 which runs OS X Lion. I managed to partition my HD without a problem as well as install Windows 7 64 bit on it. However, when I went back to try to download the Windows Support Software using Boot Camp Assistant, it downloads to about 25% stalls. It's been at that point for a few hours now and before that, I'd restarted the download numerous times but the same problem keeps happening. I also went to this thread https://discussions.apple.com/thread/3207049?start=30&tstart=0 and downloaded the .pkg file there. I unpacked it onto my external and tried to run the setup.exe on windows. However, I get the error message, "this version of boot camp is not intended for this computer model". I was wondering if there's any solution to the download problem as I suppose the second problem can't be fixed. Also, if there are any Mac Book Air 2011 owners out there who happen to already have the drivers for Windows 7 x64 and are good enough to upload it to rapidshare or somewhere so I can download it, that would be great!
