Zoombrowser EX help

I have Zoombrowser EX 5.5 for windows which came with my canon camera. I have burnt my photos to CD this morning using this software and it all worked fine. I have tried to burn the same photos to a different CD after and I get the error message “The CD drive does not support the requested operation”. I dont understand what can have happened - it worked fine, nothing changed nd now it wont work.

I have done the usual shutdown & restart and have changed the CD and haver recorded other media onto CD through the same driver to check the driver works. None has worked still getting same error message.

Please please help.
