What you do need to do with the connection installers is use them last and make sure LW is closed and not sitting in the tray (check task manager if necessary.) Ignore File_Girl's LW-fix.

With exception of 4Shared, I do not usually quote the direct download links to the connection fix installers because every time I update them, the download link changes. I usually quote the folder link address. The folder link never changes even if I update the files within the folder at the upload site. (I need to be a paid member of MediaFire to be able to update the individual files without the link changing. MediaFire support gave me nice instructions last year on how to update files but I realised I don't have those options.)
