ok, as to my knowledge, you (both of you) should have had kro/sakray in your comps already (else no qrro fer you

)
and the both of you should have two *.exe's in your ro folder, one is the patcher program, the other is the "straight to game" program...
make it a habit to regularly use the "patcher" it'll automatically download, extract, and update your qrro for you...
check around "general qro" and look for topics posted by CM regarding the patches and patcher, as i know there's already a topic there with links to kro/sakray, or the patcher itself... i'd recommend d/loading the patcher first, then extract to ro folder and patch from there first... if it dont work, then try downloading the kro/sakray (since tis a mucho bigger file

) and work it out from there, patch, blah-blah...
as long as your game is kept up-to-date, you wont encounter any errors or such, especially sprite errors, or exe errors
