FM 2010 Data Argentina 5 Levels

Hello, i have edit the File of Loco Titan, an optimazion of Patch 10.0.3 . All Leagues up to the 5 Level. 24 Legues and 456 Teams.

I have edit all Team Names exact and correct it, Missed Nicknames and Year Foundation i insert it. Home and Away Kits insert to.
After the last save, almost everyone is almost done with everything , data from the 5th level is duplicated and a great many of the 

upper levels have disappeared. Is there a tool that can process more data volumes or can simply read out the XML file?

is there no other tool that can edit the file from the editor?
