No puedo empaquetar mi documento

Sometimes a corruption is in one page. You could try the "Divide and Conquer" trick of saving half the pages until you narrow down to the bad actor. It is summed up here.

Try to export your document as IDML, then open this IDML file and save with new name and then try again on this new INDD file.

Also, does this happen with just a particular document or every document? If it's a particular document then it might be corrupted, in such as case exporting to IDML and then resaving to INDD could be tried.

Could you please provide the exact version of InDesign and operating system that you are using. Also, please provide details as to the content of your document. For instance are there extremely large Photoshop or Illustrator files imported into the document that may be causing a jam. What kind of fonts are you using? For best results you should be using Open type fonts. The more specifics you provide the more likely it is that a solution can be found for your problem.
