Personally, I prefer to use Suunto Dive Manager 3.1.0 with my Suunto ZOOP. You may want to give it a try to see if 1) it works with your computer and 2) if you like it better.
Find DM4, DM3.1.0, and DM1.6 on the Suunto website site @ http://www.suunto.com/us/products/software/suunto-dive-manager
Hope this helps.
