First Aliens now Mechs in Anarchy Online

Hi! I have a problem with Alien Invasion pack in Anarchy Online. At first, I installed the pack without any problem, but the new cities doesnt appear in the game. After that I uninstalled the whole game and installed it again, from the start. Now I have a problem with mechs and Aliens! Any suggestions? If you know what the problem is, please post it here!

Building on the storyline introduced in The Shadowlands, Alien Invasion expansion pack was the next REPLACE to the Anarchy Online game. This expansion introduced player-built cities, player-owned shops, new social interactions and clothing, and, most significantly, a new threat to the world of Rubi-Ka in the form of an alien race that has suffered tremendous pain and death because of human interference in the Shadowlands. It was released in September 2004. try to find solution for mechs and aliens problem in FAQs section on official site of the game.

Speaking of mechs.. Doesn't anyone besides me find them almost pointless?

I mean yeah they come in handy for tower wars now.. But very few use them.. On the BS it seems they are somewhat used to attack Anti turrets.. I wish they would give more uses to mechs other than just pvp
