Error 401 with Nitro Pro 13


Recommended Posts



I'm using Nitro Pro and my serial number is 5049XXXXXXXXXXXX78.

When I open the Nitro Pro, the screen will show " An error has occurred with our system. Please try again or contact support if this error persists. (Error 401) " In the beginning, there is no problem, but after 5 mins, the software is still running, but the mouse cannot use with this software. (Others are still work.) Please help me to solve this problem.


Many thanks for your troubles.

Best Wishes,

Tony Hsieh
