Switch to XSE.
I think that the error must be from the script editor, as it was said, you should change to XSE, but as you said, XSE also stopped working for me when reading the commands but I think that that XSE error must be from the download as I tried downloading an unofficial version of it and it worked.Would if I could. I stopped using XSE because it stopped being able to read the simplest commands. While checking my script, it'd say things like: 'Unknown Keyword: msgbox', and stop compiling my script altogether. Of course msgbox is a very simple and well known keyword. There's no solution online for this problem. It just doesn't recognize it. If i cannot use msgbox, there's no point in using XSE. I also tried using message and other stuff, but it just doesn't work.
