Problems with the challenge mod

I have some trouble with the challenge mod
the first set crashes
with the 3 other I auto-loose (with the deck ape-lord)
I have win XP, I have patched the game with the version 20100329,
Error message :
AppName: magic.exe AppVer: 7.0.0.0 ModName: msvcrt.dll
ModVer: 7.0.2600.5512 Offset: 00037740
Is it possible to unlock the cards without winning the challenges ?
If you want some information( journal of error, ...) don't hesitate.
Thanks
