downloaded Hrvoje`s Turf tutorial & importer , adboards importer...and both of them give me this ERROR : "Component 'COMDLG32.OCX' or one of its dependencies not correctly registered : a file is missing or invalid
follow the instructions of this site to install the missing file
http://windowsxp.mvps.org/comdlg32.htm
For this cases simple type the name of missing file in google and you will have lots of information about it.
Btw i reccomend with not using Turf Importer but Turf Maker by Monkeydragon.
Turf importer may crash your game.
About the crashes after editing with CM try to rebuild your fat with FATBH Rebuilder by Monkeydragon.
If rebuild don´t work:
-Check if you don´t have any team with more than 30 players.
-Don´t install faces with CM. It may crash your game.
