It sounds like you've just completed the Map08-10 hub. However, when you complete those 3 maps you're supposed to enter Map11. It does not sound like that's happening. Did you use any cheat codes while playing the maps? I don't believe those would cause the problem you're having, but I can't figure out why else.
As an alternative you can simply warp to Map11. Start the game, then type IDCLEV11 to take you to the beginning of Map11. Don't worry about losing all your weapons, ammo, and armor, as you get stripped of those when you start Map11 anyway.
