Messagemode keys

I got a little problem with some of my keys. Whenever I play on an etpro server I am not able to open messagemode2 and messagemode3, I also can't open my menu via my escape button nor can I send voice text with the mp_quickchat. When I type /bind y it does say in et that messagemode2 is binded to it so it's pretty weird. those things just wont popup when I press those buttons. I do not have this problem when playing on the new antipro or on an etpub serv.

Any help

tnx in advance
