The first error is regarding CBA. This typically means one of two things. One; you don't have CBA installed. Two; you don't have CBA running first in your mod line. If you have CBA downloaded and installed, make sure it is the very first thing that is loading up in your mod line.
As to some of the errors below that are related to AiA, make sure you have AiA installed in this fashion. All in Arma Terrain pack (6.5gig) --> Patch --> Hotfix. Ensure that you are merging only the contents of each folder (Patch, Hotfix) into the main AiA folder. Some of these files will overwrite and/or replace, so putting them in the correct order as shown above is paramount.
Check the above, and tell us where you're standing.
