Forums Connection Issues Freezing Problem

everytime i try to connect to a server (ive tried every server almost every server) mirc just freezes, ive uninstalled and reinstalled many times still nothing same thing dont understand because i have been using mirc for a long long time and this has never happened to me before

Is it a full freeze (ie: you have to CTRL-ALT-DEL or a reboot to get access again) or a long delay? If a delay how long are you waiting? Do you have any scripts that have on connect or on start events?
Does this same thing happen with a barebones install of mIRC (ie: no scripts)?
What version of mIRC? OS? How much ram? What else do you have running at the same time?

Let's handle those questions first, then work on any others if necessary.

First, when it freezes, try hitting control break.

Then try /remote off before connecting.

i have to reboot to gain access again, i had a script so i thought that was it at first so i removed it restoring mirc to the way it was originally didnt work so i uninstalled and reinstalled ect... its the lastest version 6.2, winxp, 512MB. the only thing i normally have running is internet explorer.

If you're using IE 7, various problems have been noted and reported, when using IE 7 in conjunction with mIRC. While I haven't heard of this specific problem with that combination, that might be the problem.
If you are using IE 7, then I suggest you downgrade to 6, which doesn't seem to have as many problems when running with mIRC.

If you're not using IE 7, however, then I'm out of ideas, as you've stated that you've tried everything that I would've suggested.
