Please stop messaging people on the boards so that they have to reply to you - you have private message'd me too. When you post something you need to wait patiently for an answer - there is no point private messaging people constantly and bugging them. If someone knows an answer, they will reply to your post
If you were banned from a channel then we will not help you evade the ban, which seems exactly what you are doing by using a BNC. If you've been banned then you stay out as per the op's wishes. Ops may ban people for whatever reason they like, even no reason or if you think it's unfair. You may try to contact the op you banned you or another op to see if you can be unbanned - beyond that, there is little to do. See this page
Do remember that channel/server/network bans have nothing to do with mIRC and nobody on these boards has any control over them.
