Ok so...A few days ago there was this annoying nooby who kept spamming a region with a lot of random blocks and I kept crashing. The faults it caused were 7 corrupted files, which includes: SLVoice, orpt.dll, libsndfile-1.dll, vivoxaol.dll, vivoxsdk.dll, winmm.dll, and zlib1.dll. I moved these into a different folder out of the SecondLifeViewer2 folder thinking it wouldnd't read tham anymore..BUT..for some reason, SL is still reading those corrupt files isntead of the newly created ones from a re-install I did. How do I remove these corrupt files, obviously the basic right click and delete doesn't work, is there another way? I don't know what the dll files do, but I can't use voice on Second Life, it says my voice is enabled but I can't choose the in and out going devices, it's greyed out, and the mic volume is greyed out, and to the right of the volume bar it's stuck on ''Please Wait'', and there is no white dot above my avatar. Any help would be appreciated, thanks.
