when i m trying to load maplestory with gameguard, windows will display 'data execution protection has blocked maplestory from loading'. However,maplestory will load when i disable data execution protection use bcdedit and enabling compatibility mode(winxpsp2) . Is there any workaround solution to enable nprotect and data execution protection runningat the same time? I have contacted nprotect and so far there is no reply.

This really needs to be answered by nProtect, as it appears they are trying to do on the older processors what DEP does on the latest processors. They may disagree, but if DEP does what they were doing, the use of their product may become moot. Again, you will need to deal with nProtect to get their answer. tgc
