Red Alert 3 Bug and Version Problem

I bought the The Ultimate Collection to get RA3 from Origin, and my little brother just simply bought the RA3 himself from Origin too, we play together without any problem, but some recent update make things change.

Now my RA3 become version1.13 automatically, even uninstall and install it again won't change anything, and with this my RA3's little loading page never display normally.

Each time after I install the RA3 and first time open it, a window asking me to log into my EA account, even I had already open the EA APP and keep it log in, it's annoying but not big deal.

And the worst is, since my RA3 become version 1.13, I could never play with my little brother again, the reason is that my little brother's RA3 is still version 1.12, and it even working without any problem and could play with others through it's version is not the latest.

I'm really love RA3 and the time playing with my little brother, but I just can't solve the problem even I try my hardest, please, somebody help me.
