To me it sounds like your missing some objects, mainly the panda objects. You can try downloading the Panda World scenario from
http://rollercoastertycoon2.com/scenarios.asp It'll install the panda objects when you load that scenario. Also if it's a scenario you're tring to load, try unzipping the file and double click the scenario, instead of tring to load it from the game itself. Hope that helps.
