All up to date then. Here's some suggestions:
1. If you have a different hard disk drive or disk partition with lots of spare space, change your download location to there via LW's settings.
2. Close LW, Defragment your Hard disk drives.
3. Download & install the LW beta
LimeWire 5.2.8 - Lime Wire as this version is faster to open & close & should require less computer resources.
4. If still problems, delete your LW preferences folder, but save your downloads.dat file; see first post of
Fixes for Limewire (click on blue link)
5. Disable Ultrapeer mode & TLS in your settings; LW's menu bar, Tools -> Options -> Advanced -> Superreallyadvanced -> Performance.
6. If still problems, remove some of your incomplete files via canceling them from the LW download window. Such as those at zero% downloaded.
