Hello, I'm afraid I cannot help you, but I too have had problems after installing 4.02. My problem involves an inability to render. When I try to render anything, I get a message stating that the textures I selected do not exist (when they do exist), Then parts of the model I'm working with start to disappear. After which the program starts to crash with endless out of memory messages. If anyone knows how to remedy this problem, I'm dying to hear from them. gorfenol@aol.com
