Counting that: (1) this is the first time I hear about this kind of issue, (2) we have thousands of users using AllMyNotes daily, and (3) we have unique highly failure-resistant database engine (read details here -
http://www.vladonai.com/allmynotes-organizer-notes-outliner-safe-encrypted-storage-format), and, finally, data file can be locked most likely by third-party applications, I can presume that it's something specific to your PC.
Either way, let's try to cover all possible scenarios - hardware and software failures. So I recommend to do following:
1. Try to
create brand new database file using menu item File -> New, and move all your data inside by copy-pasting root folder of your old data file. This will ensure that your data file structure is correct and not damaged by any sort of software/hardware failure that could happen in the past.
2. Move your data file to
different physical drive, if only possible, using File -> Save As... menu item. This will save you from drive-specific failures.
3.
Re-configure backup options in AllMyNotes, go to Tools -> Options -> Tools -> Backup -> make sure that it's configured to make automatic backups, check backup interval to be reasonable and also I'd recommend to keep backups (see auto-delete older backups option) for more that two weeks. This will give youbig amount of backup files stored in backup location to choose from in case of future problems.
Today I can only access data from a date one month back
I'm confused, are you using automatic backups and all recent backups are "locked" so that you have to go so far in the past?
In case of further problems please send over to me file named
allmynotes.log, hopefully it will contain exact reason of the issue.
