You might need to Un-install limewire and re-install it ?
make sure you have a copy of the limewire installation file before you uninstall it.
I uninstall mine once a week so that people can reconnect and download more files after they have reached there limit, i have a lot files
you might try to pause the downloads and restart them, before you uninstall it ? I am new to limewire and hope i can help others, once you uninstall it you will loose all the files you are currently trying to download, so you will need to re-download them :-( and if it says you already have a copy, choose to append a number to the new file, and then see if that works.
