I don't know if this is a PE5 or my PC problem. I shoot using (Canon) RAW format. These pics I then edit and save in either PNG or TIFF. However, I don't seem able to "save as" JPEG (from PNG or TIFF) in that when I select "save as" I do not get the JPEG option in the drop down list of available file types.
I originally got an error message stating "PE5 was either in use or there is an error on the hard drive". PE5 was definitely not in use elsewhere.
According to the PC's manufacturers tech support team, I will have to restore the PC which obviously I wish to avoid!!!
