Trivial Sublime

I downloaded them through the SDC... I have no idea what programs it installed; I just kept hitting next.

I installed Object Desktop this morning and rebooted when promped; when I did windows booted up to a desktop with no taskbar or icons, and I can't right click. My mouse works, my start button doesn't, and the only thing I can do is open up the task manager by ctrl-alt-del. I can start windows in Safe Mode. What the hell is going on?!?! Edit: I'm running Windows x64 Professional on an Athlon 3700+ w/ 1 gig corsair xms ram, so system specs SHOULDN'
