Error message after last update build 3918 to 3925

Hi each time I open flash fxp I see:
For this time I run 3918 and each time i must close update dialog box it's really boring, can you help me to resolve this problem ???

Do you have any scheduled tasks configured within FlashFXP?

If not then the quickest and easiest solution might be to simply delete the schedule.dat file from the location specified in the error message.

This error indicates that there is a problem with the schedule.dat file and saving was disabled because of it.

When upgrading to v5.3 build 3925 part of the update process requires changes to be made to the schedule.dat (which takes place on startup) and that is why you're seeing this error on startup. Otherwise this error may not of ever been triggered or seen unless you manually opened the scheduler dialog in FlashFXP (Tools > Schedule)

Thank I follow your advice to delete schedule.dat it's ok now
