XFCE corrupted session fix instructions?
 

I'm running UbuntuStudio 12.04.2, with XFCE for a desktop envionment. My system has started acting weird.
I'm not able to move or maximize windows, I can't access many of the features of my browser, like my bookmarks or history, Things are just Not Right.
I've looked around and discovered others have had this issue, and traced it to XFCE, and a corrupted session file.
There are instructions for how to fix it, but they assume one already knows how to operate within the command line, which I really don't.

The commands
$ rm -r ~/.cache/sessions/

and
$HOME/ .cache/sessions/xfce4-session-*

were mentioned as being successful, but they weren't very specific about how to use them.
I'm not sure how to go about this, and I don't want to make things worse.
Can someone walk me through this from the beginning?

You need to open a terminal window (click the Applications Menu, up at the top there may be a Terminal Emulator selection; if not, select System and Xterm -- you can also right-click on the display and then click Open Terminal Here).

You'll get a window that you can type in. Enter
(the <enter> indicates: hit the Enter key on your keyboard).

Log out and log back in. If that fixed it, you're good to go. If not, open a terminal window again and
Log out and log back in again.

Hope this helps some.
