what version??????

i updated to my cod4 version to 1.5. but now i see that some of you are playing on 1.0, some on 1.2! is there any kind of a version SR* is offically playing on?? or doing the clanwars??
but i think i will go back to to 1.0... or are there more of you playing on 1.2???

my next problem:
i just can't connect to the ventrillo server or the teamsspeak server with the adresses lion gave to us! i checked my of version ventrillo and temasspeak but it`s ok! so what am i doing wrong??

im so confused.....

we are playing on 1.0 but 1.2 is ok aswell XD
We have realised that the ventrilo didnt have a password, so we have activated that, its the one that ends in 100
ok cya
