"Rapid Miner crashes after installing and configuring R extension"

Hi,

I am trying to make the R extension work. Unfortunately, Rapid Miner crashes on startup.

I have set the system variables as follows:

C:\Users\stablum>echo %PATH%
...stuff stuff stuff...;C:\Program Files\R\R-3.0.0\bin\x64;... stuff stuff stuff...

C:\Users\stablum>echo %JAVA_HOME%
C:\Program Files\Java\jre7

C:\Users\stablum>echo %R_HOME%
"C:\Program Files\R\R-3.0.0"

any ideas?

Moreover: is there a log file to understand what happened during the crash?

thanks!
