I have a serious problem.
My favourite script: "now playing" stopped working from one moment to another... It had been working properly till this afternoon.
Now it doesn't start, and in the scripts menu it says:
"The script could not been started: it is bad, or you don't have enough priviliges to run it." (with my words/translation, coz' i'm using hungarian version)
So it is stopped.
If I use the ?bugreporter?, it says:
"The script starts
Error: The automatic service cannot create the object. (code: -2146827859)
       File: main.js. Row: 28.
Running the script is unsuccessfull"
(in my translation )
The 28th row is this:
"var fso = new ActiveXObject('Scripting.FileSystemObject');"

I tried everything: reinstallig WLM, Messenger Plus, the script, updating them etc...
If i try any other scripts, they will work! Only this 1 don't want to...
I don't know what could "damage" this script... I used it a lot... And I didn't "mod" it...

I'm using:
-Windows XP sp2
-WLM2009 (build: 14.0.8064.206)
-the latest messenger live plus
-Nod32 antivirus (if it matters) (I tried switching it off)
And I'm the supervisor of this computer, not just an user...

Any ideas? Please help me!!!!! I'm just an user, not a programmer
Sorry for my english...
