Jazz is in Harry Potter 1 pc version
 

Time has come to show you imported maps from Harry Potter 1 maps from pc version into Jazz Jackrabbit 3 alpha demo it's good news and bad news are Electronic Arts never made official unreal editor 1&2 for harry potter pc trilogy(underlicenced,but not endorsed by Epic Games) so some Harry Potter fans decided to make their own unofficial Harry Potter 1,2&3 level editor for pc version. That's the reason why it can't load maps properly just like in case of Unreal 1 pc level maps.
