Photo Lab Printing after processing

I am trying to print an image that I have edited in Topaz, but the printers comes back with a message************** ONLY JPEG AND IN SOME CONFIGURATIONS TIFF CAN BE PLACED IN THIS ORDER (my file is jpeg) THESE IMAGES MUST BE RBG (which it is) AND NOT INDEXED OR CMYK COLOR. CONVERT OTHER TYPES OF IMAGES TO ONE OF THESE FOR OPTIMAL HANDLING.

Help me I am stuck and need to order a print.
