Error when using arduino.exe or .bat file

Hello i am new to the whole arduino thing, but i can't even get it started up.

When i try to run the program i am getting an error saying: Problem getting data folder

i tried to searh the internet and this forum for any solution's but i cannot find anything.

I am using window's vista With latest java SE (java developer)

Anyone have any idea's how to fix it? ;)

Hmm.. did you preserve the folder structure when you unzipped the file? That is, if you go into the Arduino folder, what do you see? A few files and directories? Or lots of files?
