Batch Download Pictures From Website

my computer froze and picaloader was running. afterwards when i rebooted and tried to open the database picaloader would run infinitely. i opened up the picainfo.dat database and it was corrupted at the end with illegible ascii characters and i was not able to open the others thumbnail and the .plp file. is there a utility out there to repair the files or can you add a repair utility inside picaloader to repair the database by removing the corrupted sections or even have picaloader option create a backup database before running a pict query?

thanks
