Hi, it's Annabelle. I'm planning to upgrade to a Rockbox MC5 desktop for my music machine, hopefully within the next few months, and I'm wondering, would I have to upgrade Lime and Goodfeel? Most important of all, I'm upgrading from Windows XP 32Bit to Windows 7 64Bit. Are there differences between 32Bit and 64Bit operation? I currently have Lime 9 and Goodfeel 3.1. More information about the machine I'm upgrading to is available on this link. http://www.pcaudiolabs.com/quote_view.asp?quotenumber=201172214542275714 _____ No virus found in this message.
