I have had problems recently with Affinity Photo failing to open properly. In my wisdom I uninstalled the Affinity software on my Windows 10 desktop, went back to my original order confirmation and downloaded the Affinity Photo software again. The .exe file claims that the software was installed successfully. Photo tries to open, claiming that it is downloading fonts, the black background opens but the screen then clears. I expected to be asked for my `key' but it doesn't get that far. I have tried to attach the crash file, as advised elsewhere on this Forum. What should I try next?
