Hi,
I was using a community version since last 2 months but in order to get the Bot into Production, i switched from Community version to Trial version. I installed the studio but i am unable to activate it with the code provide with the installer link. I got the mail last Wednesday and i installed the Studio today. This is the error that i am getting.
Also, i am not able to activate using manual activation.
Please help.
