I started Minecraft. Once It finished opening I clicked on my inventory (E). After I clicked "E" Minecraft crashes. What does this mean?

Read the EAQ.

I have the same issue 1.4.5 works fine but i cant get 1.4.6 to work

Due to a recent change by Lex to fix some issue in windows (files with certain names aren't allowed to exist on the file system, aux is one of them), it's supposed to reobf as _aux.class.

So poke the devs about this issue.

It doesnt reobf as _aux it just gets written it files as _aux and FML will load _ names before bare names.

So, this is till an installation issue on your end if you can't figure out how to install Forge manually, install it using a launcher.
