OL, u did it wrong, first thing u dont activate it by their..., at the very beginning of the setup it asks do u want the 30 day trial or "i have a serial" and u generate the serial from the key generator, copy paste into the setup, (dont close out of the keygenerator or dont change the serial number it generated for u that u used in the setup, ull need it for later use), ok after it installs ull reach up to a part where it asks how u want to activate ur serial, you would choose activate by phone(Dont choose activate over internet lol..), then if wud give u another serial(activation number), u copy and paste it into the key generator (second box), then then u press "Generate Auth Code" on the keygenerator. and then it wud give u another serial(authorization code), this u cant copy and paste so u will have to type it in manually in the setup, after u have done that activate it and you should be all set.
Hope u understand wut i said., if not u can always pm me
