I don't know anything about that.Never had the chance to use Win7
Guess you'll have to use the other way then
For the LGP Editor you should use LGP Tool by Ficedula.It Very Easy to use
http://www.mediafire.com/?wrdcn8ch3dh7g08First,open Battle.lgp(If you didn't know,its in data\battle)
Click Extract all
Choose where you want to extract and click ok (It should be a new folder.)
The LGP Tool might look like its not responding but its ok.Just wait till it done
After that,open the folder you have extracted battle.lgp
In that folder will have LOT'S of files you'll see a rtck file.Copy it to wherever you want
Rename the new file to rtcz and put it in the extracted folder
Finally,open LGP Tool
Click Create
Choose the folder where you extracted battle.lgp and click ok
Choose where you want to put the new lgp file and name it battle.lgp.Then click save
Wait until its done
Put it in data\battle
Play the game.
BE SURE TO BACKUP THE ORIGINAL BATTLE.LGP BEFORE YOU REPLACE IT
If this too not work for you,just upload your kernel folder and I'll do it for you
