Just one question: is there a need to renew my key for wrobot after computer change? I mean my previous computer is sold, should I do smth special to make bot work on new one?

dont think so, every time you open Wrobot i think it polls the server to see if anyone else is using the key.  the old key should work on the new PC.

Hello,

You don't need to renew your key after computer change. You can use your license key on several computer/ip without problem (but you cannot use several time the same key at the same time, this is the only limit).
