If you just pruchased a swatch book, you could register for free to the Pantone Connect extension... I think you get a full year of use. But in my expierience, it is not fun to use. It does however let you add new colours to your swatch pallet. I'm not sure if it lets you download the entire colour book at once though.
In the meantime, you can add a swatch yourself to Illustrator. Since Color Bridge colours are CMYK-based, you just need to create a new swatch with the values off your new Swatch Book and name it PANTONE 2188 CP. Also: Color Bridge colours are NOT spot colours, so you leave it in Process mode.
