Digital Workshop

hi guys
last month my colleague left her work for me in CD (imp file) , I need to update that CD but after I made the updates and want to publish it gives me and error msg like (cannot create the file). Please help me on this.

Check that you are publishing to a location that exists on your PC and has enough room to save the published file.

Note you cannot publish directly to a CD drive - you must publish to a folder on your hard-drive and then burn those files to a CD using your normal CD authoring software.
