Files Say Access Denied

[SarPar]

I just got LimeWire to work with my Vista yesterday by removing the McAfee firewall. It connects now, with all the bars full in fact. But I'd tried downloading 5 different things, and everyone of them have been zip files. When I get them, it tells me that: Windows Cannot Open the folder. Access to the compressed (zipped) folder (then it gives the foldier location) is denied. It's doing this for all my zipped downloads so I can't use any of them. Is there anything that can be done with this? It's not like the ones about the music being downloaded then zipped when the PC is restarted. These are files I'm downloading already zipped, but it won't allow me to open them.
