Cannot open JPG's or PNG's in Photoshop

[Tim LaBreche]

Setting up a new iMac at my home office and installed my Creative Cloud account.

Installed Dropbox and all of my files loaded.

I went to open JPG's and PNG's in Photoshop and I get the error message:

"Could not open “file-name.jpg” because a JPEG marker segment length is too short (the file may be truncated or incomplete)."

The thumbnail previews are also not showing up in Bridge, but they do in Finder and I can open them in Preview.

The files can be previewed and open without any problems on my iMacs at work. Any thoughts?

Photoshop or Photoshop Elements? Which version?

What's the origin of your jpegs and PNGs?

I accidentally posted in the Elements forum. Sorry. I've reposted elsewhere.

The origin is wide spread, whether they're pictures or graphics I've created in Photoshop.
