Dude, face it, when you installed the game, something corrupted the install and the game got all screwed up. Now it's giving you all sorts of problems and you take your frustration out here. I can understand where you're coming from, to a point. I used to run TS2009 on a computer that was barely capable of running it, and the game sucked. it would get a fatal error every 5-6 minutes and the game would crash. I was lucky if i could go ten minutes between saves working in surveyor. I never let it go that long because i would do some great, hard-to-do thing in the game, then promptly lose it when the game crashed. Finally, something gave and the game corrupted. so i finally shelled out the money and bought a computer that could run the game. It worked from then on until i installed TS2010 and moved on to that, which also works wonderfully on the same computer (aside from a minor graphics issue, but i now know, thanks to kindly asking for help in the correct forums--TS2010 mantainence of way--that it's a problem with the computer and not one of the game itself, and i can correct it from happening now).
Moral of the story, you need to 1.) check your computer's specs against the ones needed for TS2009. If they barely meet the minimum requirements, scrap that and/or upgrade (you can either put new parts in the old computer...more RAM, better memory card, and the like...or buy a completely new one. I did that...or rather asked my parents to...since it costs less). and 2.) if your computer is up to spec (always always ALWAYS use the recommended specs as your measuring point, never the minimum, that never works out well; IE the game runs terribly) then uninstall the game, delete the local folder, and re-install. Note that when you delete the local folder, you will lose all the content you've downloaded. You can try copying the local folder into a backup folder, but i've found that only makes things worse. I've had TRS2006 crash on me twice, and TS2009 once. Every time, i re-installed and put the local folder back in, only to find that the local folder held the problem that caused the game to crash too, and it re-corrupted that game. It's better to just delete it and move on. you can always re-download what you already had. If the re-install works, then 3.) WITHOUT downloading anything into the game, patch the game up to the current patch, testing it carefully after each one. when you encounter problems, and everything else is ruled out, then you have to...unfortunately, uninstall, delete, and re-install again, this time without adding the patch that screwed everything up.
okay, that's a bit verbose, but that's basically the only way you can fix this at this point. It WILL be time comsuming, but you'll be left with a clean, good-running game in the end.
happy trainzing!
