Hi my names Jess ....
I have recently tried installing Roller Coaster Tycoon 2 on my computer.I have had it on the computer before but it got wiped off so i tried re installing it and now when it gets to about 58% it comes up with a little box saying ....

Component:English
File Group:English
File: D:Englishrct2.exe
Error: Data error (cyclic redundancy check)

I have tried several things to sort it out but nothing seems to work
If anyone knows how to solve this problem ( error ) I would appreciate it sooo much if you could contact me via email ....
