...or buy some more RAM - prices are real cheap these days. for the record, LimeWire needs 64 MB, on its own, to run on your system.
there also could be an extension conflict on your system. FAXstf is one extension that has been known to conflict with LimeWire, and must be disabled, through Extensions Manger, when LimeWire is running. you can download a shareware app, called Conflict Catcher, to verify others.
