[ros-general] 4.6 Alpha VirtualBox hang (where the heck to get 4.5?)

[fc]

Hello Folks:

(if this is the wrong mailing list to ask, please just redirect me)

Running the 4.6 Alpha LiveCD in VirtualBox (allocating 2GB of RAM and 
2.54 GB disk space, on an i7 with 16 GB of RAM) completely freezes 
VirtualBox during the install, right after you pick language.

*So, where the heck do you get a 4.5 LiveCD?*

I went through the web page (which is not set up well for browser usage 
-- to much junk bouncing around, too little content) and all I can find 
it 4.6 Alpha.

I've been to the builds page,
the wiki,
etc
and I can't find prior builds.

Little help please?

#thank you
