FATAL ERROR IN AutoCAD Civil 3D 2008: Unhandled Access Violation Reading 0x0000 at 0h

This is the error i receive everytime i try to generate setting out data for my designed centre line.Urgent help needed because am late with the submission.Please anyone.

seems like the problem i had a few days ago i wrote here too and guys adviced me to use recover command. you should try too

i have tried the recovery command it aint working.it seems like there is a problem with the software not the drawing because if i use a different cmputer with the same software it is able to generate the setting out data.

if so you should reinstall or repair your software but before reinstallation be sure that you have deleted everything (down to registery entries) related to uninstalled software
