COMSOL livelink and MATLAB 2012b

Dear COMSOL users,

I've been trying to use COMSOL liveliness with MATLAB on Yosemite (Mac Os), but I wasn't able to launch the program again first time running.

I've tried the followings:
1) To connect to the server using COMSOL server (app), the result is :

2) To connect to the COMSOL server from the COMSOL multi physics program. (Username and password are the same with the one I entered when I launch the livelink very first time.)

Is there any other way not to put username/password to run the livelink? Please share your useful experiences.

Thnaks,
