Slow download at 1 kb/s use to be 50kb/s help please!!!

I use to download stuff at 50 kb/s now its only 1kb/s. I am downloading a four star file with about 30 sources and it is downloading from 8 hosts and it still only downloads at 1 kb/s. I purchased the pro and had not problems and all the sudden this happens and I contacted limewire support and they told me to delete my preferences folder which is "c:/documents and setting/.limewire" I did this and I restarted my computer and it was still the same. The rest of my computers internet works just fine it is just on limewire that has troubles. I did not change anything or uninstall anything. Can anyone help me. Any help anyone has to offer is greatly appreciated. Thanks
