First, I have to say I LOVE Paint.net. I have Photoshop, and to be honest, I like Paint.net better.
I just updated Windows (I have windows 10 and am running on a rather new Dell laptop, like a year old).
I was running Paint.Net for years with no problem. Now, when I open it I get the following error messages (attached). paintnet1.png is first, then I click okay, and then get paintnet2.png. When I click okay, paint.net goes away completely.
I tried to uninstall paint.net, but there are two files under the sessiondata that are locked. I have no permission to do anything with them at all. They're folders made up of a string of numbers (see paintnet3.png).
The only way I can delete those files is to go into command prompt as an administrator and type in Net user administrator /active:yes. Then I can do a rd FILENAME but it still says it's there. I reboot and it's gone.
When I reinstall the latest paint.net, I can get into it one time. When I close out paint.net, I go through all of the above again, with the error messages, etc.
I'm not a saavy tech person, so if you can help me in layman's terms, I'd really appreciate it. Thank you all for all you do. This is one amazing tool.
