Nextgen Gallery albums problems

Since i had update my ngg gallery to 2.0.66.33 from an old version,
the albums in wordpress can not correctly display my galleries.
like this page:
i have see my log and it says the :
“failed to open stream:
No such file or directory in wp-content/plugins/nextgen-gal
lery/products/photocrati_nextgen/modules/nextgen_data/class.ngglegacy_gallerysto
rage_driver.php on line 563, referer: http://www.hs.ntnu.edu.tw/album/xxxx/”

the other question is that the galleries preview pictures can not display,too.
I have saw the problem php file,but I not really understand the php script.
I am confused what the problem is.
