PGE Player is not finished egnine, Will not proper work currently. You can use PGE Editor though it will create level for 1.3 and 2.0 better than Legacy Editor.
If you just downloaded PGE separately then it will be. You're best off downloading SMBX2 (from http://codehaus.moe) as that has a full working engine included.
