1.24s = That's the Shareware Demo of the game. Look in the lower left corner of the main menu to see what version you have. If the number doesn't have an "s", it's the full version.

In a nutshell, The full TSF contains nine Single Player levels, 4 Capture The Flag levels, 3 Battle and Treasure Hunt levels, 4 Race levels (well, it should, but the first 3 are missing), three characters (Jazz, Spaz and Lori), and the best User Levels at the time.
