callExtension problem

[Tory Xiao 5]

Does anyone use soulkobk's serverRestartMessages.sqf on his server to show restart messages? I always get a "CallExtension 'real_date' could not be found" error when loading the script, even though real_date.dll file is right there in the game directory. 

Any idea why ??
