Roller Coaster Tycoon Save Game Fix

[Hi Ho]

I found a patch HERE (http://www.game-revolution.com/download/patches/pc/r.htm) that is supposed to make old saved games work after reinstalling the game. The problem is when I put the old games back into the saved games folder after installing the game I can't access most of them because it says I haven't unlocked that park. The patch is supposed to fix that but when I try to run it an error comes up that says "Exception Raised - Access Violation 00000000, 00000000, ..." I know I saw directions on how to use this patch a while ago but I have no idea where and I don't know how to get it to work.

EDIT: I found instructions HERE (http://www.atarisupport.com/newfaq/rollercoastertycoon.php?browser=1&issueNum=168&osType=WINXP&pageDisplay=MAIN#faq_prodissues) and downloaded the official patch but it still comes up with the same error.
