Hello! this is my first and here my problem
so here we go my rct3 won't start ...
so i reinstalling IT and i launch the game again it's not working because of blackscreen !!
what supposed to do ?

Do you get an error message before, during or after blackscreen? Do you get blackscreen with any other application on your machine? Did you get blackscreen before reinstalling or are you only getting it after reinstall?

Before Reinstalling to ....
Before Blackscreen The Game Was Worked 100 %

What are your system specs? It would be helpful if we knew about these on your system:

CPU
RAM
graphics card
root drive capacity, including how much space is now available
CD/DVD drive if you installed this game off disk

If you don't know this information run the Windows System Information utility and you'll find the information there.

CPU:POWERLOGIC
RAM:2GB
Graphics Card:ATI Radeon HD 4600
ROOT Drive Capacity:129 GB OF Free Space

This all seems in order. You haven't given the GHz of the processor or how many cores it has but everything else you've listed indicates the processor is adequate.

Is this a new graphics card that you've just upgraded to? If so did you ever get this problem with the old graphics card?

Do you get the black screen with blinking underscore cursor at the top left, or the black screen with frozen arrow cursor? If you get the black screen with frozen arrow cursor, where is the arrow located when it freezes?

the arrow is in center
