killa_hydro2005,
Try this for your corrupted installation:
Reinstall Java using the JRE offline installer (point 1 below). Remove your current Java version before installing the new one.
Fixes for LimeWire
Delete LW's preferences folder (point 3 above & if you've used older versions of LW then point 2 as well).
Now reinstall LW & make sure to use the offline installer (not the recommended one).

You could also try changing compatibility too (point 5).
