Hi sandy, Sorry for the problem. Would you please follow the screenshot below and send feedback along with log file from the program? And please provide as many details as possible, such as your phone model, OS version, etc. Our technician will check it out. Thank you!
Phone Manager (v 2.8.0) worked great for me until I had to update iOS from 9.x.x to 10.2.1 after which everything else would export EXCEPT Messages. I found this fixed it for me: Open iTunes and connect your phone then choose Summary. In the Backups panel uncheck Encrypt iPhone Backup – you may need to Sync too. Close iTunes, restart your pc with the phone still connected and choose Trust if the Trust This Computer message appears. Start Phone Manager and Messages should now export. Good Luck, Bomber
