Can't start

Because of this:
https://www.miranda-ng.org/en/news/unknown-profile-format

But I don't know how to do what it says. What should I actually do? Like, step by step?

[dartraiden]

- find Miranda installation directory (where Miranda32/64.exe placed)
- find Plugin Updates directory inside Miranda installation
- find Backups directory inside Plugin Updates
- copy ALL files and folders from Plugin Updates to Miranda installation directory (replace old ones)

now you can start Miranda and use your profile

- go to Main menu → Database and press Compact

if you received a message about successful compression, you can update the Miranda to the current version
