BB Curve :: Can't Restore Memos - 8520?

My Blackberry Curve has developed a frustrating problem. A couple of weeks ago, the screen started fading out to white and wouldn't go back to normal operating screenThe only way to get it back was to connect it to my Mac and restart via BlackBerry desktop. All fine, but it has continued to do this on a daily basis. If I am on a call, the tell tale sign is a loud crackle, then bang - have lost all connection and the white screen of death is back. Taking out the battery and restarting doesn't fix it.I backed up my files last month and when I'd restart it, everything was restored. Until this week, that is. I can't restore my memos from the backup file and three games have also disappeared (not that they matter ... much!).

When I go into the back file, the memos is in grey (where you should be able to tick the box), with a note at the bottom that says: "Dimmed entries are read-only data bases and cannot be restored."I know there must be a way to get then back, but I'm at my wit's end. I've got some important notes on them and want them back before I replace my Curve.
