Hi and welcome !

Main question...

Have you recently 'updated' and/or 'clean installed' LimeWire ?

Tomorrow's forecast:
Sunni in places, Shi'ite in others...

Both. I updated, uninstalled, and reinstalled Limewire.

Ok, this is really frustrating. Now I am connected again. It seems that it takes a good while before it connects. Any idea what could cause the delay?

Tanks so much for your help, and sorry about the "back and forth"-thing here.. ^^

OK

And as far as the 'back and forthing goes', we have just begun !!! LOL
Have a look at this > If LimeWire Will Not Load
which you'll find in my signature in the above post.
Might as well have a look at some of the others above it in the LimeWire group.

Be sure to come back either before you try out the 'fixes' or for sure after !
