Unable to connect to EV3 via bluetooth in Matlab R2014b

I have installed the Supported packages (along SDK 7.1) for EV3 for Matlab as well as Simulink. Connections to EV3 over USB works fine but when I connect to EV3 over Bluetooth, it gives teh following errors:

>> myev3 = legoev3('Bluetooth','COM21')
Error using error
Unable to load a message catalog 'legoev3io:build'. Please check the file location and format.

Error in legoev3 (line 157)
                                error(message('legoev3io:build:CommInvalidType'));

Unable to rectify.

You may have to do some setup. See http://www.mathworks.com/help/supportpkg/legomindstormsev3io/ug/connect-to-an-ev3-brick-over-bluetooth-using-windows-1.html

I deleted other 2 Lego MINDSTORMS hardware support packages, the error disappeared for now.
