SNOOPY FLYING ACE SAVE GAME 04/06/2016

I am trying to edit my MP points on Snoopy FA. When i open the game save on the editor on 360Revolution, i get a value like this -1792460372. <br />
When i try to edit my points to any other number so i can unlock my level 100, i keep getting this error message (Exception of type 'System.OutOfMemoryException' was thrown) and everything shuts down.<br />
Am i doing something wrong or is there something wrong with the editor itself? i have been using so many different editors thru 360Revolution <br />
and i've never had this problem. Can someone try and help me with this? Thanks in advance
