I'm not sure why people were suggesting replacing memory sticks... The problem appeared to be that your graphics drivers didn't support a high enough version of OpenGL (only 1.1), and that it was failing to allocate enough memory for a large texture.
The latest posted log shows OpenGL 2.1, though, and doesn't have the texture load issue, but appears to be from an attempt to run v0.4.6 over two years ago, so I suspect you've not uploaded the correct log file from your latest attempt.
Post an actual current log, and if it has the same issue as the first post of this thread, try with a smaller texture in place of the problematic one, as suggested for the very similar issue here: https://www.freeorion.org/forum/viewtop ... 052#p93482
