I have followed all instructions, I have downloaded system check and updated preferences, and what then Im stuck at this page, what shoud I do next to make Beta accaunt??
I think you should check your games list, and see if the starcraft beta is listed as a game. If not, you weren't selected...I think you make your account when you're selected.
If you are that desperate to play it, there are cracked versions online. I won't link to any but I'm sure a Google search will come up with thousands of hits. From what I have seen/played, it feels just like Starcraft with new units and graphics. Can't wait for it to be released!
