Hello,
Please, help me to activate the programm. I use the code which was given me after registration, but nothing happend. Even option "further" wasn't active. I tried many times usinf Internet, using mail. But everytime I saw passive option "further" or if I went back and again forward I got a massage "Error is 4173. Please, contact with Courselab". I even deleted and installed the programm again, but no use.
I didn't cope and paste the code, I typed it each time.
