I did an upgrade to Windows Media Player 11 recently and if I am trying to sync Sansa C140 with some files then the process is very slow, it is taking almost 1 hour to sync 2 hours worth of music? The copying process seems to be fast but it gets stuck for so many minutes on "preparing to synchronize". I am having an AMD Athlon 2.1 ghz cpu and 512 mb ram which seems to me quite decent for the requirements. I dont know what else to do rather than going back to WMP 10 to solve this problem. Thanks for any suggestions.
