all dl's 0 KB/s now for some reason

[johnyboy]

i start up lw (just installed latest version, problem still occurs), it goes through the usual process of loading old dls etc, lw connects; green bars in bottom left, the dls appear, one starts to dowload... all's normal. then a few mintues later, as is the case as i type, there's 5 files downloading ("Downloading from 8 hosts", "Downloading from 3 hosts", etc.) but all of them are at 0 KB/s. three green bars are still ok, i'm still able to search and get results, just not download any bytes. it stays theere saying it's downloading from multiple hosts but it isn't.

it's been like this for a couple of days now. if i quit lw, restart it i can download a tiny bit of a file right after starting lw until it all stops again.

any ideas what's wrong?
