Need help ASAP!

[flvideo50]

I am working on a job with stills agin, gotta be my favorite thing to do. I am importing stills to my Rennie for a hi-lite. I imported 50 with no hitch. I am importing them in batches of 40 to 50. When I Tyied to make a CD from a PC file it said windows had had trouble and couldn't transfer them. I have tried several times and can't seem to get them to tranfer so I can burn them. I have looked at files that I just transfered with no problem and they seem to be identical to the ones that won't transfer. Does anyone have any idea what I might try? I would appreciste any help you may be able to offer. Thanks Bob...
