Severe problem installing personal data backup file

Hi, all! Few weeks ago for the first time ever, I backupped all my data from the device, then flashed the device with latest pr 1.3 and cssu-stable. Then tried to have the backup program get my backupped sms and calendar data plus phone call list back into the device. It always goes up to 99 percent. Then the device auto-reboots and I get an error message saying that backup's attempt to restore my data was unsuccessful. What can I do? Help please!

PS I understand from http://wiki.maemo.org/Manual_backup_and_restore#Calendar that it should be possible to just manually put the backupped "calendardb" file which is part of the zipped backup into /home/user/.calendar/calendardb. Problem is I can't do this since I don't know how to move the file to there.
