Hello
I'm using ''Rpg Maker XP Postailty Knights Edition Enhanced''
It all went well I even made a small introduction for my game and all... now the other day, I want to re-open my game file. So I click on the icon of ''Rpg Maker XP Postailty Knights Edition Enhanced'' And now it says:
Can't find entrypoint of procedure GetVersionEx in DLL-file KERNEL32.dll.

What does this mean!?! and how can I get rid of it... I just want to start rpg making again...
Please help me
thank you

Oh nvm! 
I don't know what happened but it's working again so...
Maybe it's because my dad did a virus scan...
