I can only suggest you do a reinstall Saz, ensuring no other programs are running.

Photo & Graphic Designer offers support for a huge range of file formats, making it easy to exchange your work with other users and programs. This includes common bitmap types (eg GIF, JPEG, BMP, PNG, TIFF, PSD, and RAW photos) and key vector types (eg PDF and AI/EPS, SVG, and EMF/WMF). For text Photo & Graphic Designer can import Word files (.doc and .docx) and supports RTF (Rich Text Format).
