ZTE Connection Manager quits unexpectedly when opening to register internet key from Wind, on Macbook OS X Yosemite version 10.10.1

I installed ZTE Connection manager (MF667) and when i open the app in my applications to register my simcard it opens the page but then keeps on quitting by itself within 2 seconds saying that "ZTE Connection Manager Quit Unexpectedly" I have tried un-installing and re-installing again, it doesn't make any difference.

The ZTE Connection Manager is for the internet key (aka dongle) i bought from Wind (Italy).

Anyone, pretty pleaseeee help....(puppy eyes and if ur cat person then kitten eyes ^^)
