Severe problems with Sprite Backup Please help!

[Penny]

Ok, I have Sprite backup and I have done several backups which were successful. I recently had to take my 6700 into the sprint repair store so I had to reflash to Original rom (was running BigJ AKU 3.5) any way after I came home I went to restore it and when I hit restore it either tells me the backup file is not for that device that restoring it may cause harm or it restores but everything is messed up. Some of the same things are there and some aren't. Some programs will not open says they are missing. I can't even open my calculator. My mail problem is that I had dates in my scheduler and I need to get those! They are very important. What am I doing wrong or is there any suggestions?
