sachiaiko,
If you have the latest version of java then you should be ok to download. Are you getting Limewire from the offical site? It shouldn't be corrupt if you are dling it from the main site.
Remove that version you got, delete all the leftover LW folders, then start again from the official site to download the program.
You are trying to download the basic version correct? Dont keep reinstalling the version you got because it could have been corrupt. Delete it and startover with a new install.
Edited to add: Let the install be placed in a downloads folder in your c drive. That way, you'll be able to find it.
