Vegetation won't regenerate

[20ninescene]

Hi guys,

I have a problem: I'm working on the vegetation for Roma Surrectum III and the Rome Total Realism project, but suddenly rome total war won't regenerate veggies anymore, I tried everything but it still doesn't work =c
for information I'm running the game in 16 bit colors mode and no antialiasing and my operating system is windows 7. I'm really, really desperate, so if you have don't know any tips and you know how to generate vegetation, would you like to generate the vegetation for me? If so I would be very thankful.

edit: I solved the problem myself
