1. Maybe you have to activate/deactivate, so please have a look there:
2, Sometimes, we know in the meantime, the "opm.db file" is the culprit. In this case you should delete it.
3. Did you already try "uninstalling and re-installing"?
Be careful with (de)installing aso. by (de)installing by your own resources. As much as I regret it and as strange as it may seem I fear it's a challenge for Adobe's Creative Cloud Cleaner Tool.
Sometimes - for whatever reasons - CC doesn't "want" to work. In this case you should CC completely delete and reinstall by help of Adobe Creative Cloud Cleaner Tool. (A try to uninstall by own resources is not enough!)
I quote: Adobe Creative Suite Cleaner Tool helps resolve installation problems for Adobe Creative CloudCS6) applications. The tool removes installation records for prerelease installations of Creative Cloud or Creative Suite applications. It does not affect existing installations of previous versions of Creative Cloud or Creative Suite applications.

Okay, just found the solution:
The problem was the folder ~/Library/Preferences/Adobe InDesign/Version 10.0/de_DE
That folder was already created but owned by "root"
sudo chown myusername de_DE
did solve the problem – InDesign starting now
Thanks for your hints, Hans-Günter!
We were just posting the same time. Fortunately I didn’t have to got through any deinstalling, I will avoid that as long as possible
