Is limewire opening up for you ??
If it is go to your incomplete folder in your limewire library and click on one of your incomplete files and click on explore, that will take you to your incomplete folder outside of limewire, see if you can delete the offending file...
The 1.5.11 is the JS2E (it was the link I gave you and yes the offline installer was the one)...
Also make sure you delete your preference folders...
