Downlds refuse to reload (click on link). However LW 4.12+ will normally continue from where they left off. I guess it depends how old your other version was. The new LW might not work well with incomplete files from a version before version 4.9. Also, be sure you uninstalled the previous version properly. For versions 4.4 or later, the installer will remove the previous version at beginning of installation. However, if your previous version was earlier than 4.4 then you'd need to use the Add/Remove control panel to remove the previous version depending upon whether you used the standard version or international version. The international version had an uninstaller in the program folder. The reason I'm discussing this is the previous version might not have been uninstalled properly & might be launching at the same time you're opening LW 4.12 & thus running in the background. Control-alt-del & see how many limewires are listed.
