before installling fs2crew for pmdg 777 my ts2 was working fine while i was doing a route on ivao

after installing FS2CREW teamspeak 2 can recive voice but cannot transmit it 

the green circle is appearing when i press PTT key but no one can hear me

i have this problem at last week and the only solution for it is to format whole computer 

i dont need to format it again just i want to get rid of this product .. bring my teamspeak 2 backkkk helpp

FS2Crew doesn't install anything that would affect teamspeak, ie., any kind of system file.

So it's something else.

As a start, maybe try mapping your Teamspeak transmit key to something else:
