Sorry to hear you are having trouble.
Am I the only one having a problem with Deskscapes 10 beta freezing when using the random background option? Have a brand new computer running Windows 10 with an Nvidia GeForce GTX 1060 video card. Starts fine and works for about 10 minutes before freezing and the only way to get it going again is to reboot.
After the purge and reinstall, what is 'freezing' - the transition from one image / dream to the next or the PC itself? If it is the former, the transition of, is there a particular dream that is triggering it (the one it freezed on)? Does a restart of Windows Explorer fix it:
Also, this was an interesting post from another client:
