Hi yes I was checking you had a genuine versio of Limewire pro so that does'nt seem to be a problem
Responses from pro can take a while and often help can be obtained more easily on the forums.
I find Exiting does not always work as expected, If you have no uploads or downloads taking place in the Mac version, LW will usually shut down on exit. I have given up trying to work out if this is correct. If I want to shut down soon, I select disconnect , which stops new hosts from connecting, but established hosts can stay there for hours!.
If I want to keep LW running in the background I simply minimise it, Windows is no doubt a bit different, but I suspect the close down thing has not quite been perfected
Individually shared foders may be a new thing in .30 I know nothing about it I'm afraid
Let us know if this helps.
