Rollercoaster Tycoon 3 error :(

Hi There guys,
OK so my issue is i have a 2009 MBP which i have had Rollercoaster Tycoon 3 installed on since 2009 and had no problems running it ever. Then recently i bought a new One Terabite hard drive and 8GB or ram for my computer and since i did the reinstall when i try to run RCT3 all i get is a light blue screen that flashes one shape and size then another shape and size then back to the first then to the second again and then just goes black. Now i believe that there is an error message behind this because i saw a glimps of it during the flashing but don't know what it says because i have to force shut down the program to get out of it. I have also tried to completely delete all the files and reinstall so any help would be appreciated.
