ad-free, with licence

Hello,

I bought the license for ad-free IM,  i placed licenze on Messanger admin, and I accepted ( Messanger is Enable).

But when I try in fronted use Messanger, give me this message:
"This widget is not registred"

how can I do?

Goto the folder ray/modules/im/xml and delete the file main.xml

Then upload from new dolphin pack and set permission 666

Goto you admin panel and again register it.
