Hello Олег,

Uninstall all Incomedia WebSite x5 programs installed like the Free and Demo Versions, and then delete the installation folder present in Program files. When these folders are deleted, proceed to delete also the Incomedia folder in AppData\Local\ and then download the most updated version from your answers.websitex5.com profile in the "Downloads" section.
You will need to deactivate the antivirus and firewall and then run the installer, with the right click option, as administrator.
Follow the registration procedure and once installed, run the program again as administrator with  the right click option.
When the program starts, open the project and then reload all image by pressing CTRL + Preview.

Please let me know if it works.
