Ive tried and read through loads of "fix's" on this forum, and others, but none have worked:S i didnt have McAfee pre-installed, nor do i have it installed now, i have port forwarded the port 6346 for TCP and also UDP, ive disabled my firewall and av and still limewire doesnt connect, it says "loading internationalization support" for ages... and then when i exit it it just says "limewire shuting down" with the loading bar, it just goes on forever... this is bugging as it doesnt work on my computer neither my sisters vista laptop, also i have tried running with windows xp compatability and using run as administrator, ive also deleted the pref file and it still didnt work... i dont know what the problem is, im thinking about downgrading to windows xp soon if i cant get limewire to work.
Any help would be appreciated, thanks
