Please use "Save Project As" and create new names when saving projects created by previous versions of MAPP Pro.

If you are having difficulties with Zip files created in previous versions, extract the xml and dxf files so that they are separated, open the xml in MAPP Pro, re-import the dxf and re-save your project as a zip file using a different name. REMEMBER: Zip files are not overwritten, they are updated. We recommend that zip files which show errors andwere created with previous versions of MAPP Pro should be deleted after the project has been repaired.
