CTD due to video memory?

[Aquilae]

Well,I do have Alexander installed,cause I bought me the TW Eras package.
I doubt that my RTW,BI or Alexander are cracked,cause I didn't see any crack files,and I ordered it from an online game store.
I suppose it is an original new copy.As for the modesty patch,well I taught it will do no harm.
Oh,and I hope that my version of RTW is already patched up,cause when I look at the version it says 1.0.
So,all this being said,what do I have to do now?
