Sorry, there aren't any LW technicians here
Try this:
1. Reinstall Java. Use the JRE
offline installer here. Remove your current Java version before you install the new one.

If you've only used very recent versions of LW then the folder will be in point 3's location. If you've used much older versions in the past, there could be a folder in both locations.
Fixes for LimeWire
Deleting this folder will kill all of your settings within options...you'll have to go back thru & reset your options afterwards.
3. Now reinstall LW & make sure to use the
offline installer (not the recommended one).

A corrupted installation is a corrupted installation...whether you have Pro or basic.
