Hi all, I have a sony NWD-B105 DMP and up until now has been working fine,when i connect it to my pc it will not auto transfer,an error keeps flashing up "Cannot launch due to unsupported os",so I reformatted the player,hoping that this might help,downloaded all the software, and its still not working!! I am not sure if this has anything to do with the problem a couple of weeks ago i downloaded Service Pack 3 from microsoft,any help would be appreciated!
