Well, sometimes Rct3 is slow because sometimes it takes a bit to start up depending on your computer. It could be because you didn't wait long enough. Try waiting a while. Hope this helps! P.S. I bet if you wrote that many words you could get some money on a essay LOL!

If you consider 3 minutes of waiting long enough...

My friend's notebook is much slower and does it just fine.

I wish I could help, if I experience it in any-time, I will let you know how I fixed it

Try pressing the SPACE bar. I'd copy and make a download on my site for you of the Rct3 files and tell you to delete yours and put mine in, but I have platinum so it probably wouldn't work. You could find something like that for deluxe on the web. Some of your files could be damaged!

As I said I reinstalled the game several times, copying the 'healthy' files over and over again. It might have something to do with other parts, be it software or hardware, of my PC. I hoped someone could read something suspicious in the dxdiag.

Here's good advice: go get as much money as you can for the game while it still has value. Save up money and buy another one. That sounds like the best idea right now.

I replied already but it used to this on my old pc and it works now, that goes to prove the you don't need a new game/s disc, just depends on the condition of the CD drive or the CD alone.

I appreciate every bit of help you guys can give me, but I can almost certainly rule out problems with my CD. As I said, no problems on other PCs.

Sorry to say, but it looks like you'll have to settle with Rct2. Or get a new pc.

Try doing a forced msi-uninstall of the game, then re-install it.

It's also possible that the registry for your game has also been corrupted. Use a registry cleaner, if you have one. Hope it helps.
