i have os, cable., limewire pro. I recently moved. i think that must be when problem started but not sure. i live in a house. i had an airport..but not sure if its hooked up anymore. i went to preferences..and bug, etc...and all three said true. I dont know who my internet service provider is...but i'm sure it hasn't changed since before i moved. i did the test and it worked. i dont know what security i have or where to see if there are firewalls(there is not a brick wall showing on limewire. I don't know what p2p sharing is.
thanks for your help.
