yeah, first time i downloaded it, it didn't work, the file wasn't complete
so i downloaded it again and when it came to activating i was taken to the webpage and had to try a few times
clicking back and refreshing a bit
i entered my details and clicked next and it errored
then i clicked back and did it again and it worked
then i clicked the next button to get the activation key and it errored...
then i clicked back and it resent info and then i got the key

maybe it worked for me almost the first time because there weren't as many people trying to activate it since most of the users were probably asleep at the time
