Hello,

Thank you for your bug report.

I have released a new build to address this issue (5.0.0.3776)

This issue was caused by one of the changes in the new build

Improved the method and logic behind the "application password protection" feature to lock all data files during the switch between encrypted <> non-encrypted mode. When sharing the data files with other machines or syncing via apps such as drop-box, BitTorrent Sync, etc. could result in mis-matched files where some data files were encrypted and some are not. This was only an issue when multiple copies of FlashFXP were running across different machines and the "application password protection" was set, password changed, or turned off.

One rather important condition that I missed while testing was to verify the behavior of new installations where the data files don't exist yet. This of course triggered a false positive resulting in this mishap.
