New to this forum, and new to NFO

I have just purchased a VDS (unmanaged) package, and here is my issue.
At first, I attempted to install a GUI via " apt-get install xubuntu-desktop "
This gave me package errors, where some files may have been missing.
So I proceeded to change the /etc/apt/sources.list file, which was fine, however, now with the same install command im not even able to get any packages downloaded.
BUT that is a side note. I realised that NFO has Virtual CD-Rom drives that can be loaded with any OS in the list...
So I chose Ubuntu Server 10.4, and went through the installation process.
Now that the installation completed, I simply removed the Disk Image from the Virtual drive, and issued a server reboot, at which point, I get put into the main linux black log screen, where it asks me theMCXP Login:
No matter what I type in there, I cannot get passed that spot. I tried ' root ' with the password provided in my control panel, I tried the new user account that the ubuntu install asked me to create, nothing seems to be working, and I dont know what to do.
Any help would be really appreciated!
EDIT:
Now I can no longer access SSH or VNC...
