It won't let you downld what? The "Offline" Java or the Crap cleaner or the "Offline" LW installer?

What do you mean you can't access those files? Your LW prefs will be either here C:/Documents And Settings/your_username/.limewire or C:\Documents and Settings\*yourusername*\Application Data\LimeWire
Your Application Data folder is hidden so you can access by using the search function & using options to show hidden files & folders. Then select limewire from the application data folder in the search results & go to file>delete.
