The Wonderland Board

For some reason, When I installed Return to Wonderland (I may have removed it before), the game loads fine. But, for most maps, the "violation" error occurs and maps which previously worked and it never occurred on tested maps before when I use to use Windows XP (now I use Windows 7). Also, when a fireball hits a wooden box, the game crashes for some reason every time...

Please help me,
Thanks.

Edit- Crashes also occurred on non-custom maps

Here, every "map" is called a level.

How much RAM do you have? What graphics card do you use?
