TimeLog not opening after power blackout,

Timelog Basic, corrupted the log.dbf file when the power cut out and the software was open, was able to copy a log from my backup collection and then reindex their database.

checked for swipes from today missing the IN because the clock had no power but advised there is a backup battery that can turn the clock on long enough (15 seconds) to swipe a card on it then it shuts off. should last then for approx 8 hours.
