Hi Dennis
I see, you have an earlier version of Colossus which uses the Kontakt player sound engine, (Later versions moved over to the East West Play Engine) hence the link to NI.
When you have Colossus up and running, update the Kontakt Player to the latest version, (4) as while it won’t give you any more dedicated Colossus features, (These are determined by East West) it is more efficient with disc streaming, CPU use and Ram. (You can load and use more sounds compared to the older versions)
Hope this helps

Bill
