Problem with Cinnamon + Thank You

[Mehdi Bateni]

Hello to all;

I am new to freebsd and after installing it to my virtualbox, I used MATE DE for some days. It works great. Today, I tried to install cinnamon de on my freebsd by running this command in shell:
$ sudo pkg install cinnamon
After installation, at the login, I have a option to choose mate: session or cinnamon. MATE still works well, but cinnamon crashes at startup and shows nothing. 
Can you help me with this problem.

Regards
Sushiant
