This is the error message I get. Not sure what to do now.Ive uninstalled LW etc and tried setting it to the default saved folder but not working.Any advice?

Im using the latest LW
Vista
3gb ram

I'm having the same issue. I also noted that LW on the spashscreen (when it starts) is fogged out. I'm worried about malware.

I also get the same error. Does anyone know any solutions to this?

Check this link out (invalid save folder)
or try this :-
Open Limewire
click on Tools --> Options --> Saving
Now you will see a Save Folder and in the Folder window provided it will show you where your present downloads are being saved:-

[eg] C:\Documents and Settings\Username\Shared

To change this click on Browse and find the Folder you wish to save your files in. Click OK

Also check out this link (new location of LW saved and shared files)
Hope this helps
