Can't start Wander beta16 on Windows 7 Thread - Wander

Hello! I purchased the game yesterday but I can't start it.
I get to the loading screen, hear the music and then the game crashes.

The error log:
Unity Player [version: Unity 4.2.2f1_54f0fc09defb]

wander_beta16_win.exe caused an Access Violation (0xc0000005)
