Markzware can troubleshoot and fix InDesign, using Q2ID (Quark to InDesign) and FlightCheck (Preflight for Print): 

What do Q2ID, Acrobat PDF reader, Adobe InDesign troubleshooting, and preflight have in common? An InDesign file fix.

Markzware‘s QuarkXPress to InDesign conversion software, Q2ID, is an InDesign plugin for data conversion. Graphic designers and creative professionals can use Q2ID to convert QuarkXPress to InDesign for the print workflow. (We hope your publishing workflow is preflighting for print quality control, as well.)
The Markzware File Recovery Service provides file recovery for bad InDesign files. This no-cure-no-pay service can fix bad Adobe INDD files and also recover corrupt QuarkXPress projects.
