Is Limewire connected now ?

The downloads can be just unlucky choices.

When you first installed did you allow contentfiltering ?

Or accidently messed up the licence issue ?

BTW are these downloads started while using the old version ?

If so Check the incomplete folder in limewire and see if they are red. If they are then try and cancel all the downloads then highlight them in the incomplete folder and press resume. There is a slight chance that they never start due to some curruption happening when switching versions (they will start again from scratch if so). But often it works.

If they start from scratch cancel them. Then delete entire incomplete folder while limewire is closed. A new one will be created next time you start Limewire. Just search for them again same way you did before.
