i have installed ccsm on my ubuntu 11.04 to have some desktop effects.
then when i used it and make some changes it actually did something strange.Actually i made some changes in Desktop section.

Now there is no menu or the title-bar is coming.
so i cant access any of my applications and cant even shutdown or restart the pc as the title-bar has gone.

also the keyboard shortcut for the terminal is not working.
what can be the solution to this ??

Thanks in advanvce.
