I've installed the new patch (1.5 Beta R6)... I join the voobly's rooms normally but, once im inside the AOE room, I can't X in it says "You have a different version than the host"... all the players appears with 1.3 version and im the only one with '"1.0 CD version"

What can I do?

Thanks!

Maybe you never installed 1.0c version of Conquerors?
You can find it here:

It's a calculated guess, I am not from tech support, hope someone else can confirm this if it's right...

yes i've installed, the problem happens in Rooms with the "1.5 Bets R6" Patch.. dont know why

hi
uninstall the patch. reboot. enter a lobby and let voobly install it. try

just try it... still doesnt work

What else can i try?

I assume your game is not a legal one (free download) and it has some custom editing in it, like a previously installed offline mod, or a file corruption (or may the patch corrupting it, as the patch is made for legit CD copies). You can try reinstall the game fully and maybe use 1.0e patch instead, and switch back to 1.0c, then join lobby and download UP1.5
