I know some pirated versions of the 2k and 2k3 RPG Maker series were rather buggy, so you may have downloaded one such buggy pirated versions.

It could be some problem with the installation or how the events are being handled within the games.

If you're running Vista, that could be an issue as well, since Vista sucks ass and isn't compatible with smurfing anything because they expect everyone to cater to their software, rather than make an operable OS for the god damned public...
