Thanks, but how I could start my FIRST topic? I had none topics posted.

To start you own topic, you must have the status of MEMBER. It takes 50 posts (replies in other topics/threads) to get it, so until then, you'll just have to ask your questions in a Topic (thread) that closely matches your problem.
Sorry, but due to the spamming problem, that is the way Captain Sim have chosen to deal with it. :(
