Mathieu think it's a window resolution problem.
Open your PAME folder, and to starter.fps/client. Then open the prefs.cs (with notepad) and change $pref::Video::resolution and $pref::Video::windowedRes as followed :
Save the file, launch the PAME and tell me if it works!
Then, to play you map, copy it in Penguins Arena: go to the folder "Frogames_PAME\starter.fps\data\missions" of the PAME, copy the .mis and .ter files of your map and paste it in the "PenguinsArena\starter.fps\data\missions_moding" folder of your copy of Penguins Arena.
