Password cannot be entered into MATLAB LiveLink

Hi,

Whenever I try to start a MATLAB LiveLink (be it over the "COMSOL 4.4 with MATLAB" icon or manually) the command window lets me enter a username, but as soon as I want to enter a password, no entries are accepted. I can write whatever I want without it being shown in the command window. It thus becomes impossible to start a LiveLink application.

I am using COMSOL 4.4 and MATLAB 2014a. The MATLAB root is configured in COMSOL.

I would highly appreciate your help.

Thanks, Moritz
