I bought Tomb raider Legends some days ago. I finished the first 3 missions, but now I cant continue as the game does not load the file:
Error code:

Exception code: Access violation (c0000005): (Read of address: 0x00000058)

CPU info:
EAX = 0x00000000
EBX = 0x000000a0
ECX = 0x011585d8
EDX = 0x00000008

EDI = 0x010c5f10
EIP = 0x004561c4
ESP = 0x0018e99c
