Why does my connection to lime wire keep dropping off is there now a block on file sharing programs?

No there is not a block on P2P sites, the problem could be that : 1 There are too many people on the same time, or 2 that your server is overloaded, what I would do is download and install FROSTWIRE which is free and much safer than Limewire, and does exactly the same, Music, videos etc:

your isp does things like that depending on the company and the amount of downloads

there is advice on file sharing sites regarding changing port numbers etc

you could find if your isp is known for doing that by reading others' reviews

Frstwire IS better for avoiding viruses too but why not use uTorrent

No, there are plenty greater that use comparable technologies (called peer-to-peer), with some differences to a topic. there are additionally courses that enable you to proportion data in a different way (like having a dropbox)

Install Blubster for the time being, deny the free add-on toolbar when installing because their adware.
