Hello,

I've been using Limewire for ages, and yeah, I know what a firewall is or how it should be configured. I never had problems with limewire under Mac (10.5.8) or Windows or with any router I've used so far. However, Limewire suddenly is reluctant to build up a connection which has worked the last day I've used it, and I didn't change anything in the properties. So I downloaded the latest version again, manually changed the connection properties, forwarded a different port, switched PeerGuardian off, switched it on again - nothing. I've no clue what to change to make it work again.

Gz

Which version(s) of LW are you running?

Perhaps start here: System details - help us to help you (click on blue link)

Like I said, I'm running the latest version of LW for Mac. I guess that should be 5.5.13

And well, off course I could post details like the ram of my MacBook, but I highly doubt that'll help. The same client works perfectly fine when I visit a friend, and it used to work in my own house as well. I've had an interim tenant in my house, but since he neither had acess to my MacBook nor to my router (well he was from india so you'll never know, but at least he shouldn't have had) that damn program should work exactly the way it used to before the interim tenant was here.
My "firewall" is LittleSnitch as it always was, yes Limewire is allowed in there. My provider is a german provider and definately not blocking me since he isn't allowed to do so. And just like I said - everything is configured the way it always worked. Except that the configuration status in Limewire keeps telling me that the connection is building up right now and never finishes.

Try this then: Deleting LW Preferences folder in OSX
