It could be so many things.
If we were sitting with you, at your computer, watching you try each step, we might be able to help you. But we are here, at home, and you are there, in your home, and we cannot see you try each step.
So to help you, we need to know
exactly what steps you are trying, 1, 2, 3. Then maybe we can say "hey, you missed step 1.5 - try this"...
Your English is good. We can understand you pretty good. But you need to explain more what you are trying so we can help you better, aye?
