GRoucho ... thanks for the update. Whatever your problem, Installing pro will not help it. I suggest you remove all vestiges of your scam Limewire, (mainy the programme and the preferences)..., remove all your bowser cashe, Delete all cookies run a complete virus and spywire check on your computer and once your computer is runung as it should, download the basic Limewire from
www.limewire.com using the second (offline) installer.
Also please tell us a bit about your computer, ... mainly processor speed, RAM, and free space.
It is worth pointing out that using Limewire will slow your computer down to an extent, but unless you have limited resourses on your computer, this should not be "intallerable"
