Open RCT2 blocked by Comodo

How can i run Open RCT2 in Comodo. I have allowed the application to run but each time i do the screen goes black and i have to re boot the pc as the ctrl alt delete wont work.

Open the file list and change its rating to trusted or you can add an ignore rule to the sandbox to prevent it from being sandboxed as well as create HIPS rule and treat it as an allowed application.
