Just installed OpenRCT2, but when I try to launch it a dialogue box displays "Unable to find RCT2 installation directory. Please select the directory where you installed RCT2!" as well as a blank command prompt-esque box. It then brings up a box to select the install directory, but when I select it nothing happens, leaving me with the command prompt looking thing. I can launch the regular game perfectly fine. Any help? Its the Triple Thrill Pack off of GOG if that helps at all.
