this has probably been asked a million times on here,
but here goes anyhoo!!!!

my laptop recently had to be re-started so i therefore had to re-install limewire.
everything seems to be ok i get to the pick language which is fine,
but then when i have to pick folder for things to go into i do the usual (just ok'ing it)it then says unpacking files as usual only to have an error message come up?

i've re-tried time and time again and the same thing keeps happening i tried changing the folders for the files to go into and although it allows the download im only getting one green bar on connection??

bear in my mind im a computer idiot so need things explained in an "IDIOTS GUIDE" stylee.
