Error -199 on launch after install completed

Had been running previous versions of Limewire (e.g. 2.1.x) without problem, but tried installing latest release. After install completed, launched program but instead get error -199. Tried reboot, no effect. Downloaded fresh copy, deleted previous install and reinstalled, no effect. Noticed that min. memory set at 384K and max. mem and preferred mem. sizes set at N/A and boxes greyed out. My guess is that this may be source of problem, but never checked previous versions to see if they are programmed in a similar, non-standard Mac OS fashion.
