Model Simulator and Gradient Boosted Trees on v9.3

Hi,

One year ago, in RapidMiner v9.1 i created a project with a simulator on Gradient Boosted Trees Model. 
Now, I've upgraded to RapidMiner Studio 9.3 version and the simulator doesn't work.
Is it possible use simulator and GBT in v9.3 or get rollback to v9.1?

Thanks.
Michael

    Hi,

    Looks like your installation got messed up as Studio does not find shipped extensions anymore. Please delete the installation folder and install Studio again. (your settings & data are saved in the USER_HOME/.RapidMiner folder, so they will not be lost if you just remove the installation folder).

    Regards,
    Marco
