Lester said:It has become permanently now. I think I made a mistake. Well, I am not bother about it as long as it doesn't affect the game.
Well, i have my Win2k in spanish here, but i will try to explain it anyway, to remove the permanent change that you did to that type of file you have to:
(the names may vary, i am making a real time translation )
Enter in "My PC"
Select from the menu "Tools"
Then go to the last option "Folder options"
Then select "File Types"
There you will find all the types of files registered into your machine.
Just look for the name of the file that you want to change (for example "File .CSA") and erase the entry.
That will remove the association between an extension and a program.
Be carefull, this change will also be permanent.
