Running VirtualBox VM host on ReadyNAS Pro

Ok, so during my numerous attempts to install VirtualBox on my Ultra+, here's where I stand and I need some assistance from the community.

- Before going on this Journey, my FW was at 4.2.19, and I ran into quite a few issues attempting to get VB installed; so I saw a few posts where ppl were having success with FW 4.2.17, so I figured a downgrade wouldn't hurt.
- I proceed with the downgrade and now I cannot access my NAS via GUI, but can still access via SSH., Not exactly sure what I may have done to the GUI, but I need to get it back.
- Also, everytime I try to do an apt-get -f install, I get the following error msg:

Linking and byte-compiling packages for runtime python2.4...

Any guidance on this will be appreciated :)
