Error during install of komento 3.0.2

Hello,

I have this error when i try to install Komento by the Network :
The MD5 hash of the downloaded file does not match. Please contact our support team to look into this.
By the Komento Full Install zip i can install it
but just after i have this message in the Komento Dashboard :
"Your current domain is not listed in our list of supported domains and you will not be able to utilize the versioning services. Please enter your domain name in your license area to be able to utilize our services"
Where i must write my licence number ?
Best Regards
Arnaud
