When I try to download Optfine Ultra A2 for 1.4.6, it doesn't work. What happens is this:
-I go to the minecraftforum.net Optifine page.
-I click the "Download" link under "OptiFine HD A2 Ultra for Minecraft 1.4.6"
-I get to adf.ly and click "Skip ad"
-I click "Downloads" at 'optifine.net'
-I click "Download" next to "OptiFine 1.4.6 HD U A2"
It takes me back to the same place as step three, and it runs in a loop. It doesn't download.
This happens in Firefox and in IE.
The "mirror" download link does the same thing.
