Passolo 2018 license activation

I wanted to open Passolo 2018 Network license and now it says I need to activate my license. But in the RWS account, it says my license is activated. Wenn entering the activation code, I get an error "Activation failed. Please provide quantity less than or equal to the remaining quantity 0."

But no one else is currently using the license, it's only used on that machine.

Thanks for your help!
