After successfull restoration and after affects

Hi there,

I have restored a Drupal 7 site and now having problem with creating new objects!
Getting This:
1)
PDOException: SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'vid' cannot be null: INSERT INTO {node} (vid, type, language, title, uid, status, created, changed, comment, promote, sticky) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3, :db_insert_placeholder_4, :db_insert_placeholder_5, :db_insert_placeholder_6, :db_insert_placeholder_7, :db_insert_placeholder_8, :db_insert_placeholder_9, :db_insert_placeholder_10); Array ( [:db_insert_placeholder_0] => [:db_insert_placeholder_1] => mpaudio [:db_insert_placeholder_2] => en [:db_insert_placeholder_3] => PushItToTheLimit [:db_insert_placeholder_4] => 1 [:db_insert_placeholder_5] => 1 [:db_insert_placeholder_6] => 1350723305 [:db_insert_placeholder_7] => 1350723305 [:db_insert_placeholder_8] => 1 [:db_insert_placeholder_9] => 1 [:db_insert_placeholder_10] => 0 ) in drupal_write_record() (line 7036 of /var/www/drupal715/includes/common.inc).

2.) All links on Sub Main Menu are showing but not the content, it could be edited and save, but not snowing after klicking on the link!

3)All audio video data are showing playable

4) Front page and numbering of front pages working

This is my very highly Experimental Site on learning the way to internet "Enlightenment:-))))

Please have a look to understand the given problems http://www.nirmana.de

Could anyone help in this regard please?
The problem is, I have tremendously huge data on this site and it'll take lot of time to copy of all this data to new site which I have already have:-))

Kind regards,
