Activation required for second macuser?

Hello all,

tried searching but didn't find anything...

I got an C1Pro License and all works well wiht my MacbookPro.
Now i get some new business starting with digital support for photograpers and is created a new macuser therefor on my MBP, to cut my private things from my business...
As i startet the C1 a License-Window came up. Is this right? Need a new license for an other macuser?? Thought it was 1 license = 1 user (as real person) = 2 computers...
