4K Download quit working after Windows 10 and Adobe Flash Player Update 09/11/2019

Love you 4K Download program, but had an issue this morning 09/11/2019 after a Windows 10 and Adobe Flash Player Update.
When I opened 4K Downloader and paste link, it would not download and just gave an error message. I was wondering if this is normal before I activate the paid version and get rid of the expensive real downloader I've been paying for the last 5 years. Like I said love the program and just need to know if this is normal and a fix will be provided.

Thank you
