Try restarting your computer. I think your problem can be easily fixed

First, turn off Steam. Completely sign out and turn it all the way off. Once you've done that, click the Start button, and select My Computer. Under "Hard Disk Drives", double click C:/ and from there you should double click Program Files. Under Vista you'll want the x86 version of Program Files. Find the folder "Steam" and double click it. With Steam still being turned off, delete the file named ClientRegistry.blob and start up Steam. It'll have to update, and just let it do it's thing.

Or in short, navigate to C:/Program Files/Steam and delete ClientRegistry.blob

In my experience, this fixes like 99% of Steam related problems.
