Re: Indesign CS6 crashes when copying pages between documents

I would try another one with each of these documents.

1. Create a new document with 2 pages.
2. Name the master pages so, that their names are not conflicting with neither of these 2 document’s masters.
3. Delete every style in that empty document, also any swatch
4. No drag the pages of the first document into such an empty document.
5. Do the same step 1 to 4 with the second document in a NEW empty document.
6. Now you have 2 new documents. Take care that no conflicting master names appear.
7. In each of these documents create in each style panel a folder and drag all used styles in that folder.
8. Save both documents
9. Try again to insert the pages of both documents.

Otherwise, it this does not work out, could you send me via private message the files or a link. I would check it with a Debugging Version of InDesign (InDesign DEV) I can use to find errors.
