galaxys2help

I have a samsung galaxy s2. i cant get my phone to work in pvt session with a performer. I can see the performer, and the performer can write to me. The problem is that i can write, but i dont get the send button to let the performer to see what i wrote. I got adobe flashplayer and adobe air. i have contacted the support on the site and they cant find anything wrong on the site. just now i got my phone back from service and its updated to android 2.3. Now i cant even stay in pvt session for more than just some seconds and then im back in the google search for the internett. it wont let me stay in pvt session or the site at all. Can anyone please help me with this?
