accidently Deleted /usr/share/themes Content
 

While i was trying to free rootfs space,accidently deleted all content of /usr/shar/themes..
now the progress bar,icons and all styles are missing,
it also shows "missing image" on the starup screen...
i tried reinstalling maemo alpha n beta themes by running
apt-get install --reinstall hildon-theme-alpha
still the default theme is not back....
i can use all the function,but evrything looks like the windows claasic style
......
