Invalid jpg

I have been using Storyboard for a few months now and this is the first time I have had this problem. I am importing my drawings from Photoshop CS5 like I always do and this time I get a warning message that the files have an invalid format.
I can open the same files in every other application, and I can still import my other jpg files created in PS. I’ve tried re-saving the files, and also “save as” with the same file name.
Any help would be appreciated. I have a client waiting on this. Thanx!

Just found my trouble…
Evidently I used a “/” in the folder name where I put the images. It made trouble accessing the files.
All fixed now!
