Hello , I recently found out about second life and today I downloaded the SL viewer (18.104.22.168262). The viewer strarts normally but when I log in it starts to show some random shapes with no meaning .The maps , control buttons , etc. are normal but I can't see even my avatar.My computer meets the minimum requirements and some components meet the recommended requirements.I'm using Ati Radeon 9550 Graphics Card and I have the lastest drivers installed .Can you tell me what causes this problem and how can I solve it . Thanks P.S. I can upload snapshots of the graphics that the viewer shows but the function is't available .
