Games start then crashes on menu

[DanteFromfield]

Hi !

I've got a problem with my game since 2 days.

I've played this game for a week without problem.

But now, every time I launch it, it freezes on the menu and crashes a few seconds later, opening a dialog window telling :
"Crash!

The game just crashed and created an error file,
please send this file to error@hammerwatch.com to
help us fix it"

So I found the error text file and it's saying :

--- UNHANDLED EXCEPTION - 04/03/2015 15:20:41 - HMW 1.3 ---
System.OutOfMemoryException: Out of memory
  at (wrapper managed-to-native) object:__icall_wrapper_mono_array_new_specific (intptr,int)
  at System.IO.BinaryReader.ReadBytes (Int32 count) [0x00000] in <filename unknown>:0
  at ARPGGame.ModificationList.LoadModFile (System.String filePath, System.Security.Cryptography.MD5 md5, System.IO.MemoryStream iconDataToFill) [0x00000] in <filename unknown>:0
------

And I noticed the games uses 2.8 G from my RAM when lauched.

Can someone explain me my it uses so much RAM and how to fix it ?

My computer specs :

MacBook Pro
OS X Yosemite 10.10.2
2,6 GHz intel core i7
8GB 1600 MHz DDR3
NVIDIA GeForce GT 650M 1024 MB
