Cant Click on Install Button.. Why

[ChiNa]

Dear vBulletin.org, I cannot click the install button, and I cannot enter some of the threads, and I have activated my account, And a license as well, here is the message i get:

You do not have permission to access this page. This could be due to one of several reasons:

Your user account may not have sufficient privileges to access this page. Are you trying to edit someone else's post, access administrative features or some other privileged system?

If you are trying to post, the administrator may have disabled your account, or it may be awaiting activation.

I would be appereciated if the permissions were openned, Thank you very much in advance,,,
