'Revolution Slider not working anymore after upgrade from Contao 4.4 to 4.9

After my contao upgrade attempt from 4.4 to 4.9 the revolution slider plugin stoped working. I also don't see it in the contao-manager and this page suggests, that it was maybe installed manually?

The current version is 4.6.4 (26.11.2014) tested for the ancient jquery 1.9

Anybody knows something about this and has a hint if it can be fixed?

As it turns out you are using a "Premium Contao Themes" theme - thus you need to follow PCT's official instructions on how to update a PCT installation from 4.4. to 4.9. At the very least you will need to manually update all PCT modules in system/modules/ as far as I know. You can download the latest version in the customer section of PCT.
