Please help.  I have been working all day and did a very stupid thing where I changed the time stamp on all my pictures at once and found that all COMMENTS I had written under file properties are GONE.  Is there anything I can do?Need...more...info...gasp  

Operating system / antivirus & antispyware protection / SERVICE packs installed / when did it start happening / did it ever work right / installed any new software?

Do a system restore to a point prior to the problem starting:

Start / Programs / Accessories / System Tools / System Restore / choose a restore point.

Alan <>< :-)XP Pro SP2.  I did it myself.  I changed the time stamp on all the photos at once and lost all the comments I had typed in under the comments section on file properties for each photo.  There is no restore point that I would want to use.  I was hoping it could be reversed in some clever way.  If you think I am screewed, please let me KNOW and will have to redo it all.

ThanksI tried the restore points but it did nothing.  It is treating the pictures as files that were saved once again under the same name.  If there is a way to go back within a group of files to restore it at some point of evolution, then that may be what I need but fear it is not to be.  Tell me if you agree it is hopeless.  THANKS
