Error Setup CallSpawnServer: unexpected response: $0

[solitaire71]

I removed MM3 and want to install MM4 because I wanted a addon for the lyrics but I get a small window that says Setup CallSpawnServer: unexpected response: $0.
I don't want MM5 because there is no "all" button anymore.
I am on windows 10
What happened? thanks

Hi,
First thank you for continuing support of using MM all the from MM3.

Re CallSpawnServer: It is most likely not MM issue, but rather Addon settings where its migration did not passed to MM4 correctly.

Re ALL button: MM5 have it and behave like MM4, but for folders (because we introduced folder browser too) it is left to be optional Switch above folder browser track list and can be triggered on/off with top right Folder icon (Plus = enable list all tracks in subfolders, X = disable all subfolders tarcks listing and list only tracks in current folder).
