was your old version 4.12.14??? you should be able to download from that site i gave you. not too sure why you can't. this is the exact page that contains that version. Download LimeWire Basic 4.12.14 - filehippo.com
once you're on the page, there is a green column on the right hand side that has all the versions on limewire listed. at the top of the column it says to download this version...click on that and you should be able to get your older version.. if your older version is not 4.12.14 than click on the correct one first and then click on download this version.
I couldn't remember exactly which version i previously had so it took a few installs and reinstalls of different versions. only that one version works for me!!! weird huh??? Hope you have better luck this time. i know how you feel. i went nuts for several days trying everything!!!!! lmk how it goes.
