If I were you I would download RTW patch 1.5. This fixes all the glitches and problems in the game. If you want a more balanced game (and better) I highly recommend RTR Platinum Edition. You can download it from the Mod Downloads section of this forum. It unifies Rome inton one faction, and adds a few others: Illyria, Bactria. I also recommend Naval and Metropolis Mod(makes it so only a few settlements have walls, whihc makes for a faster game, and adds a new farming and naval system with several new building lines and about 10 new types of ships), and the 4 Turns Per Year/Roman Leadership (makes it so 4 turns = 1 year and adds a series of traits and ancilliaries that allow you track how long your Generals have been leading troops and adds ranks for the Romans + tracks your legions and armies) Mod.

You can find all these Mods and the directions for install in this post:
