Why has my creative cloud stopped syncing?

Hello,

sorry and in this case I would do the old fashioned way (with some steps are written in the new link from above) and download a really new trial version of your program(s) in question and change it/them into a "real" version later, BUT because you said, that you "re-installed" already, so it become a little bit complicated. It would be necessary that you have to use "Adobe Creative Suite Cleaner Tool".

Here an advice for that (The order varies depending on your individual needs. Please read all my proposals first, so you can better choose the first step:)

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 Cloud and Adobe Creative Suite (CS3-CS6) 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.

Please use: http://helpx.adobe.com/creative-suite/kb/cs5-cleaner-tool-installation-problems.html   and follow the prescribed sequence of operations

4. If necessary and for further questions click through http://helpx.adobe.com/contact.html and if "open" please use chat, I had the best experiences. I quote from Preran: The chat button is activated as soon as there is an agent available to help.

Good luck!
