Im the only person in my organisation with Project Professional 2010 and have to save my .mpp files in 2003 format so that others can open them. Ive set my version to do this automatically but sometimes when I try to save a file using 'save as' an error message appears to tell me that "Project doesnt recognise .mpp format and to save it in another format". Does anyone know if this is a known issue and what do I need to do to correct it?
