Problem with Image Processor

[crossbone]

I usually use Image Processor to apply an action on tons of files on CS2. When I upgraded to CS3, I simply copied the actions over to the new action folder. Problem is, with long actions, CS3 doesn't close each file after it has performed the action unlike CS2, leaving the desktop filled with processed photos. Also a dialog box appear at the end with the message "Sorry, I could not process the following fileslist of files)". still, the processed files are saved in the destination folder. But here's the funny thing, when I run short actions, everything is ok.
what could be wrong? I tried changing a few things in Image Processor dialog box but always get the same result. again, with shorter actions at the exact settings, the results are fine.
