I've been trying to locate a version of Basecamp that will run on XP SP2. Garmin tells me that those versions are no longer available and that SP3 is required for their current version. Net 3.5 isn't a problem, I already have that installed; I just don't want to mess up a perfectly good system by installing another Microsoft update. 

Does anyone know of a source for an SP2 compatible version of Basecamp?

Thanks....
