I have done these steps but no dialog appears allowing me to delete preferences.
I had also tried the manual method and that did not work.
Keep holding the keys until you get the dialog box. You may be releasing them too early.
Double-check your fingers. Sometimes people are on the wrong keys.
Thank you for replying.
I had tried 5 times and had someone watch me. Held those keys for a long time waiting to see if the dialog box would appear, but it did not. So I called Adobe.
I just got off the phone with Adobe technical support.
The customer service rep fixed it manually similar to what the steps some people indicated earlier in the thread. She renamed both the Library folders in Cache and Adobe Indesign by adding a .old. Then restarted and it worked.
After a few failed attempts, and with lightening speed of pressing the suggested keys, I was able to see the "Delete Preference" message, but deleting the preference didn't solve the real problem, that the 100 plus layers of documents were not showing in the layer panel, so I could select and merge them to flatten the document for the printer. Someone said that Preferences are not related to the issue.. A friend suggested that I didn't need to flatten the document, because it gets flattened when you export it in PDF Print file. I hope this is correct and I am sending the document to the printer in a day or two. Thanks for your input.
