Can't launch game "Error at hooking API 'NTProtectVirtualMemory'" *FIXED*

My siege won't start and just gives me the following message:
"Error at hooking API 'NTProtectVirtualMemory'
Dumping first 32 bytes:
4C 8B D1 B8 50 00 00 00 F6 04 25 08 03 FE 7F 01
75 03 0F 05 C3 CD 2E C3 0F 1F 84 00 00 00 00 00"

Any known fixes?

EDIT: Restarting the PC appears to fix the issue, I will leave this discussion here for anyone else who gets the issue
