I found out how to fix Blizzy's toolbar, just go to your KSP game folder > GameData > 000_Toolbar then open Toolbar.version with notepad (dont set it to always open) and copy \/ and replace the stuff in the notepad for this
{{"NAME":"Toolbar"},{"URL":"https://www.blizzy.de/toolbar/Toolbar.version"},{"DOWNLOAD":"http://forum.kerbalspaceprogram.com/index.php?/topic/55420-110-toolbar-1711-common-api-for-draggableresizable-buttons-toolbar/"},{"VERSION":{"MAJOR":1,"MINOR":7,"PATCH":12}},{"KSP_VERSION":{"MAJOR":1,"MINOR":1,"PATCH":2}},{"KSP_VERSION_MAX":{"MAJOR":1,"MINOR":1,"PATCH":99}}}
all he did was mess up the file and ksp does not reconize it so it wont work no matter what game version
