"JPEG File contains unsupported features"

[charliescoffee]

I'm transferring a .xar document from one computer to another via a USB thumb drive. The file is open and I've been working on it in Xara on one computer but when I try to load it onto the other I get this error message. The document consists of a few shapes I designed in Xara, one with text repelling, some text and several JPEG's. I've tried eliminating various elements from the document but get the same message. I'd appreciate some ideas.
