No launcher after upgrade!

[Rokit_Armor]

So I saw there was a button on update manager that said new version available. I say what the heck, I'll upgrade. I am (was) using 9.10 netbook remix. After I did a few tweaks with synaptic etc to get the upgrade to go through, I am left with no launcher, and an error popping up saying cannot load applet GNOME-GoHome (or similar).
Did the automatic upgrade thing just install desktop 10.04 over my 9.10 NBR????
How the heck do I fix this? Should I burn an ISO of 10.04 netbook and attempt to upgrade from there?
I cannot lose the files that are on this partition, I have access to them currently and would like to keep them available.

Well I corrected it easier than I expected- win-R for command prompt, 'sudo synaptic', uncheck ubuntu-desktop (mark for removal) check ubuntu-netbook and install the subsidary packages.
Now just to tweak all the other little things to where they were.
Like I accidentally unchecked the system folder in the main menu editing app, so now I can't access it to add it again via launcher, does anyone know how I can get to it now?
