I have changed internet provider and now I cant download any new stuff but my limewire is still there and I can play all my tracks I have already downloaded is this because I have changed provider and is there anything I can do about it? Thanks

Is your LW connected properly (all green/blue connection bars) & are you seeing lots of search results?

When you click to download, do files move into the download pane? If not, try the advice here
License (click)

Or, do files sit connecting for ages & then get stuck needing sources forever?If that's the case, you're probably seeing fake files.

If you're searching for music files, use the All Types search & search for artist or album rather than song title. Go for a file with 10 sources or less...stay away from the files with huge numbers of sources.
If you're searching for video files, always chech the file with Bitzi before download. If a file has heaps of sources but no Bitzi rating, chances are it's a fake.
