Well...
(btw... NEVER start a sentence with, "Well,..." !)

1st, my every condolence for your sentence with Vista... Don't worry, parole is available... It's not for life !

'Explorer' is just the thing you use to drive around inside Windows... NOT Internet Explorer... That's different.

When you double-click (if you have Desktop Icons showing on your screen) on My Computer or My Documents you will be using Windows Explorer to 'navigate' around your folders and files...

Best thing to do (no offense) is to STOP internet activity for a while... This will be safer for you... Learning how to 'drive' your Windows Operating System NOW will save you years of pain later !

Another btw... Probably best for you to post general questions in the Tips & Tricks Forum here in these Gnutella Forums...
You'll get a bit more attention and it will be from all the various 'p2p client' users... Not only the LimeWire folks !

As far as listening/viewing is concerned, FORGET LimeWire's so-called built-in player... In fact, forget ALL built-in players in ALL p2p client programs !!!
They're ... er... garbage.

Use Windows Media Player or WinAmp or numerous others...
And, read here, in Tips & Tricks, about CODECs and other amusing things you need to know !

¡ luego !
