I had Unity Web Player installed into my Computer, before I bought the “Unity” game engine myself. The moment after I downloaded the Unity Game Engine, I couldn’t play any online games that use the Unity Web Player. They just show a blank white screen, does anybody know how so fix this? I seriously doubt that I am the only person who has had this problem.
The webplayer shouldn’t break just from downloading some file from the internet.
Please file a bug report with reproduction steps and make sure to add the logs Unity - Manual: Log files to it.
See: http://docs.unity3d.com/Documentation/Manual/WebPlayerChannels.html.
Select the release or stable webplayer.
