Impossible to continue to modify 1 page

[Eddy DELAMARRE]

Hello,

 

I'm modding a document, 20 pages.

I have add and delete a lot of thing like texts, picture, or  complete pages.

I'm working on it since maybe 2 weeks.

this morning I did some work on it, gone for lunch, and since I'm back, the page I was work on is not anymore moddable.

The error message is " Unable to initialize Object tool. This document could not be modified "

I need to mod this page again, but I don't want to delete it and recreate from 0.

 

Thanks for your help.
