I just got a Sandisk ultra backup 64 GB and after installing the newer version of your backup software (http://mp3support.sandisk.com/downloads/sandisk-backup-pc.zip) i get 2 issues:
-The backup button doesn’t work, is not the key, i got 10 and it doesn’t work in any of them. (i have windows 7 64bits).
-No all the folders are mapped on the interface to chose what to backup. I wanted to backup C:\Users\velascop\AppData\Roaming\Microsoft\Signatures but Microsoft under Roaming doesn’t appear.
