I can't get SL voice, and I get the following "Error Opening File for Writting" I tried disabling my anti-virus already, and re download the viewer, but get the same error. I can get the viewer working, but certain features like Voice Chat are absent. I think that is because of the files that i can't get to install on the viewer. These are the files that will not open and install: zlib1.dll winmm.dll vivoxsdk.dll vivoxoal.dll ortp.dll libsndfil-1.dll SLVoice.exe

My voice does not work at all in SL. I have tested the microphone, and it works. I logged off and back on with the mic plugged in. I have even re-installed the viewer. I have gone through all the tutorials in preferences. My Input/output devices are set to default, but to the left of the "my volume" bar it says "please wait" in green and will not let me slide it over. I cannot initiate any calls to anyone, or receive calls. When I got to voice settings it says that "No one near has voice enabled" even though I am in the middle of a group of people who are chatting with each other on headsets, and I can't hear them. Doe anyone have any suggestions at all?
