You can’t import any Messenger Plus! scripts or skins anymore, getting an innocent message box like this one?
You will have to repair the internal shortcuts for *.plsc and *.plsk files.
This should fix any wrong shortcuts so you can import scripts and skins correctly again.

It can occur when you tell Windows to open *.plsc files permanently with, e.g. WinRAR, and later you try to set it back to MPTools.exe, but that won’t work.
