The situation is this: AutoCAD 2002 suddenly cut down electricity. Then turned on the computer and one file with which worked it is impossible to open. But he is and weighs 4 MB. And when in AutoCAD you try to open in a window of preview shows that there is something. And when you open swears on the way and opens the empty document!
I tried to use the recovery team and the audit did not help. I opened in newer version but too all uselessly. In the Internet I found mention of the program AUDITDWG but it didn't help! This program only damaged to me the file (copy).
Any way to cure this disease?
