Can't update Unity to 3.5.5f3

I have Unity version 3.5.5f2 installed. Every time I open Unity, it asks me to download 3.5.5f3, so I try downloading. But it stops after 6 MB or so. I tried copying the URL into a download manager (http://netstorage.unity3d.com/unity/UnitySetup-3.5.5.exe), but this link always gives me 3.5.5f2.

How do I properly download/install 3.5.5f3 ?

Since around 2 hours ago the download link has been fixed. I just confirmed downloading it again brings f3.

Also, this patch might be just “An issue was fixed with the Asset Store windows on retina displays.”, as Na’Tosha said.
