I am aware Charter is not an especially p2p sharing friendly ISP. Problems 'might' be related to Charter.

Deleting your LW preferences might help.

Occasionally removing the occasional Ultrapeers from your Connection window may help to remove poor behaving or spam UP's. Especially those that are older than LW 4.18.8 version.

I have heard searching the same thing over & over can for some odd reason get your specific search temporarily banned from a particular Ultrapeer. So waiting several hours or until the next session on LW might fix that.

Edit: seems WW's fix worked for you. Good to hear.

(BTW the reason I edited out your email address is to stop the people who scan forums for email addresses to sell to marketers.)
