Using LW basic you can download from a max of 8 per file. Using Pro a max of 10 hosts per file. If you are in Ultrapeer mode and are using pro then I think it's 14 hosts per file.
What it means is that for some reason you are not running as an ultrapeer at moment. Reasons for that could be varied. Such as firewall interference. No need for ultrapeers in your area at the time. Or your uploads or download bandwidth being too busy within LW. Go to LW's menu bar, Tools > Options > Advanced > Performance and make sure Ultrapeer is enabled. If it is then, close LW. Try deleting your LW Preferences folder whilst LW is closed; instructions here: Point #2 & 3 in Fixes for Limewire (sample image included at bottom of page.)

first it would say in options connection speed:
dial up
broadband
t1
t3

now only

dial up
broadband
this could be the problem, because i didnt have any less than 14 hosts before i took the new version, and ultrapeer isnt disabled..
