Itranslate4 plugin does not word with Trados 2015

Dear Colleagues of Sdl community,

I have had the itranslate4 plugin installed on trados 2015 beforely, although not being for this version. Do any of you know how to install it? I do not have WS nor other automatic translation tools nothing more than the memory plugin.

Do any of you have some idea?

Thanks before hand.
