Melitabel,
1. use the following site (
http://dustyfeet.com/edge/) to download the update file. for some reason the other sites either have an incomplete file, or my downloads just didnt complete as they were suppose to.
2. use a usb stick format it with fat. go to my computer, select the drive that is for the usb, right click on it, and select 'format', under the options it will default to 'fat32', manually select 'fat'. place the update file in there. whatever you do the file should read update.zip. if you are not sure, under the usb explorer screen, go to 'tools', 'folder options', 'view' and locate 'hide extensions for known file types' and make sure its UNCHECKED. and then make sure the update file reads, update.zip.
3.turn off PE. connect the usb stick, and press hold menu and rotate keys, and then switch the power on button. continue holding the menu and rotate for approx 15-20 secs and you should see an update processing...then you are done. hope this helps. thanks to all who have helped me.
