New Editor ( JCE )

I have installed the Template Hotel.
I use Joomla 2.5.14
I have installed the JCE Editor version 2.3.3.2 and select unter "configuration" the JCE
But in all Articles and Modules there is another Editor displayed?
What must be done for using the JCE

You need to set it as default editor for you user account settings

i have set it as standard in the config.

Yes, but enter your user account settings there is that setting also if it is set than it will win over default setting

in the user account settings i have also select JCE.

That should do it , you should ask on their form about that because that is caused by some bug or error.
Try also this, go to Extension Manager, Database tab then if you see some link saying something like click here to repair database click on it
