Yes, I have updated all skins.
Interesting that I stated that it is appearing on YOUR demo. So you have your project.
Besides, this is occurring on my project when the project is not running and the skin manager is not active. That should not be too difficult to understand.
Here are the steps that I took when I installed this version.
1. Uninstalled.
2. Ran clean for the runtime bpl.
3. Ran build for the runtime bpl.
4. Ran clean for the design bpl.
5. Ran build for the design bpl.
6. Ran install for the design bpl.
7. Downloaded the skins library.
I NEVER saw this error on 10.25.
I request you make 10.25 available for download again and the previous skins, too.
This is because I feel that this issue is confusing to you and will not be resolved anytime soon.
