DomuS3D doesn't start and splashscreen remains block while loading.
First of all remove the remporarry file from the folder "%appdata%\maticad\domus3d" and "%localappdata%\maticad\domus3d\x64" before to retry.
Disable all the antivirus or malware software installed because they could block some file or folder.
If it persist try starting DomuS3D using "administrator" user. Could be necessary to check if this is a problem on the window user.
If persist we suggest to save a backup of all the database and reinstall the software.
