error starting conn for the first time

Hi dear conn Users,

I installed conn 16.b under MATLAB R2014a. Added the path in matlab. When running conn through MATLAB GUI through "conn"
I get the following error descriptions displayed (see below). Conn GUI is opened as well.

Should I use a different conn version. What can I do to resolve this issue?

Thank you in advance for your help and I am looking forward to your input.

cheers,

MR
