Hey Guys, I was confused like hell when I was installing this patch with a hot head....its better to start all over again calmly
Here are the steps you need to perform in order to cleanly install this patch:
1) Install a fresh copy of Ashes 2009 (In "C" drive)
2) Extract BIG EDITOR rar file in any folder (i extracted it in the FOLDER which also contained the file async.big)
3) Run Big editor and open async.big located in the game installed directory
4) You will notice that as soon as you open the async file with big editor, a CACHE file appears in the same directory
5) Without doing anything else, copy and paste the cache file (ONLY) in %temp% folder which can opened using the Run command in the startup menu
6) Extract the Revolution Studios rar file in any directory (I extracted in the game install directory)
7) Open the Installer.exe file A black screen will appear and it will automatically start extracting all the files into the temp directory... (normally, it will take around 10-12 minutes to complete and after that the black window will close by itself)
8) Voila, now you'll be able to enjoy Ashes 2009 with this new Patch!
This worked for me perfectly! try it out
