Unity download stops for no reason?

I keep trying to download unity. However, when I start the installer (in browser), it says something to the effect of installer integrity being bad, so it shuts it down. It always stops at exact 327 mb downloaded out of 1.2 gb, when it reaches 327 mb it just says that it is done downloading.

Anyone have any helpful hints on what to do? Thank you for any info in advance!
