X notifer for GMX ( read other thread but i need some newbie help please if someone can help me please.

Hello

I am hoping someone can help me i am a old old user of notifier but i have never ever had to use a script . recently I have joined GMX and i found a script ( not sure if this one works or not ) i am Not using the newest version of notifier as it is odd and very very slow and doesnt' open my mail correctly or click where i like it too so i prefer to use the last version as i am finding the new one is not getting along with this computer at all and is not correct in looking and i can NOT get ou of it to stop it once it starts checking like a ' disable' like this other one.
