G-lined is a global ban, that dont have anything to do with mirc, thats the server closing your connection.. look for the networks www page, but first, scan your computer for viruses online.. a good scanner is this one..
click, and remember allways have a virus scanner running in the background.. and dont take files from ppl you dont trust.. and dont click on urls sent to you by somone on irc..
you can also try remove all the wirerd signs in your nick.. only use plain text for nick and identd, then see if it works.. /identd on "your ident here"
