OK, the smoke cleared and I realized it's in the Apple menu control panels(duh). Tried to add Quicktime, first got a dialog box asking for extension and has boxes for file type and application. Don't know which extension? Closed window to look.Afterward couldn't get this box to reappear. A different one"Add translation preference" comes up.Tried stuff but don't understand what it wants. Bottom line -files still won't open. I can drag them into Quicktime and they work, but I've wasted hours and still don't have the pathway.(I don't do this stuff every day.) Am I in the right place? I thought this was the Limewire support forum. Do Limewire techs give help here or am I dependent on the kindness of strangers? This is very frustrating when a Read Me document with a configuration setup for the pathway is all that is needed, but isn't in the folder. Any clear info regarding this would be greatly appreciated. I want to like this program but right now it's a pain.
