How to fix a corrupted schematic

Hi,

I have a problem with a corrupted schematic. I run oaScan to check the errors and I got the following log:

*****************************************************************************

I tried to repair it using -repair but I was not possible. Is there another way to recover this schematic view?

    Two recent (ish) posts on this: first and second. See the advice in those.
