When i start my Arma2 CO with JSRS.....
But what is warfare2 vehicules?
Are you 100% sure you are running a CO install (A2 and OA combined)? Cause the errors seems to indicate you are missing some Arma 2 files.
To make 100% sure you are running CO just check the editor to see which islands you can select (you should be able to select at least takistan and Utes (+some more of course).
Also, there are some special installation notes for JSRS, did you follow these correctly?
Looking at your previous topics, do you already have Arma 2? Cause a little while ago you did not.
