unable to register free orca

Hi i am unable to register orca forum script from unity license each time it gives me prompt that orca is successfully registered but when i log in back in the admin panel it prompt me with 'your orca script is not registered' with red background help me plz

I'm having the same exact problem.  After inputing the 'free' license from unit, it says it is successful, but then goes back to the red screen.

I was able to get this to work. 

Originally I had set the 'conf' directory chmod 777

This didn't allow for the license code.

What I did was to set the actual file - 'params.conf' to chmod 777, which is in the 'conf' directory.

After that, license was accepted and able to use 'Manage Forum'
