You might still have the older versions of apt and aptitude in your
package cache. Check the output of: 

ls /var/cache/apt/archives/apt_0.6.46.4-0.1*
ls /var/cache/apt/archives/aptitude_0.4.4-4*

If you still have the two .deb files then you can install them with:

dpkg -i /var/cache/apt/archives/apt_0.6.46.4-0.1*
dpkg -i /var/cache/apt/archives/aptitude_0.4.4-4*

Another possibility is to add a line for "testing" to your
/etc/apt/sources.list, run "apt-get update" and then do

apt-get install apt/testing aptitude/testing

Officially, downgrades are "not supported", but I think in this case it
should work out.
