I deleted your email addy as its not a good idea to put those into your post, there are bots that wander the web looking for email addies to spam. If for whatever reason you want all replies to your post send to your email, there is a box to check for that on the page where you created your post. (they will still show up here, they will just also be emailed to you)
If you click on "how to install" to the left on your screen here, or click
here it will take you step by step on downloading and installing mIRC.
Not to worry, like anything new it only seems overwhelming at first
