I've seen a lot of problems with downloads and connections on the Vista support forum. I have no problem with this, my problem according to Best Buy geek squad is my DVD won't load the driver so I can use it is because Lime Wire is the problem. My son uses it to download and has for the past 1 or 2 months and no problems. It was this past week that the DVD problem arose so it may or may not be Lime Wire causing it. I have tried to uninstall and reinstall the driver or update but to no avail. I bought this system back in April this year. Any help on this issue would be most helpful.
