When I changed the template to dnv1, my pligg page is down and showing the following message,

Warning: file_get_contents(./../libs/lang.conf) [function.file-get-contents]: failed to open stream: No such file or directory in /home/.parody/blogyou/blog-you.com/digger/class.config.php on line 49
Could not open ./../libs/lang.conf

I have no solution about that, and can't figure out the root cause of it, afterwards, I re-installed the stuffs and start again, but when I do the same operation, the fails come out again, and I can't change back the template to the previous one, moreover, i can't open any pages of my sites, with showing the above message again, always.

Can anyone tell why this happen and how can i recover the sites as well as preventing this from happening? Or else, I have to install it again. :'((((
