In the middle of running Photo Ai using sharpening v.2 and upscaling 2x the process aborted twice and knocked out PS. I do not think this was a PS issue. Please check to see that upscaling works with PS as it is supposed to do in version 2.0.2.
To use the Upscale filter in the PS plugin, please use the File > Automate workflow rather than the File > Plug-in Extras > Process with Topaz Photo AI workflow.
I did that, but it still crashed twice. Just mentioning it as I know you are working to perfect the product. Larry
