Hopefully someone can answer my question (resume incomplete files)
 

One day while using Limewire, it encountered an error and I had to terminate the program. When I resumed Limewire it was unable to resume my old downloads. So I took it upon myself to find the incomplete files in the library and resume them manually. None of the files resumed showing ANY progress(they all showed 0%....many of them were more than half completed)
The files are displayed using red text for all the files but in the Library shows the amount downloaded in kilobytes.
Can someone PLEASE tell me how to resume the files again from where they left off? I'm really hoping I don't have to download some all over again(I already have started doing this for some files but if I can get some info on how to resume them from where they left off it''l save alot of time for me)
Useful advice will be greatly appreciated.

You've already found the useful advice.

However, the info on the 4.13.3 beta version Lime Wire » Features History does mention " Fixed reading old downloads.dat files."

So, perhaps that will help, but generally I expect old downloads to be lost if I revert from a beta version to the older standard release.
