My copy of Limewire 4.8.1 often closes on its own, without me doing anything. It shuts completely, not just minimises itself to the system tray. Any idea how to stop this? Will upgrading to Pro help?

Also (and I'm going to post this in another thread too, but just in case someone spots it in here and can answer), it seems that each time I close Limewire (or it closes itself) the save directory switches from the folder I've specified (My Music in My Documents) back to the default (the Shared folder Limewire creates, buried deep in the computer). Any idea how to stop this?

Thanks in advance to anyone who can help out this newbie!
