Sharpen AI no longer opens

I bought Sharpen AI less than a year ago and now it opens with a blank white screen which is only visible when hovering over the thumbnail on the task bar. I’m a Windows user. I’ve uninstalled the program, reinstalled it and also installed two updates. Nothing works. Can someone give me some advice please? Gigapixel, which I bought at the same time, is working fine.

Did you get a fix for this? I’m having the same issue.
