Well I don't know where the locked topics are but I see one in the Advertisement board. According to the advertising rules:
1. Your forum most be hosted on createaforum.com to post in this area.
2. Do not bump your topic up
3. Do not jump into other peoples topics to advertise your forum
You probably posted in your topic again so rule #2 would cause your topic to be locked.
Also, a topic about this shouldn't be created, contacting a moderator or an admin around here should help you.
