This could be because your internet is dropping it's connection for a moment and the download management software that you are using does not support Resume Capability. I recommend that you download a program called Free Download Manager (FDM) which supports this feature as well acts as a download accelerator. You can download it by clicking the following link: Free Download Manager
Now that you have Free Download Manager you can try and download Limewire from a torrent or a different location. Here are some links that you can try:
1 - Limewire 5.4.6
2 - Limewire 5.2.13
3 - Limewire 5.4.6 (Unofficial Download)
4 - Limewire 4.18.8
If none of the above downloads work, i recommend that you try using a program that i personally use called Frostwire which has the exact look and feel as well as the same functionality as Limewire. You can download it by clicking the following link: Frostwire
