1. you are not using the latest launcher
see log:
[22:54:46] [sEVERE] Launcher Build: '0.5.4.9'
2. to be honest, your log does not qite make sense, because
[22:56:18] [sEVERE] (MAtmos : INFO) Update version found: 11
[03:23:55] [sEVERE] Failed to move stack for autoreplace, despite of prior tests.
Which indicates 5 hours of running minecraft...
Also, there is no apparent reason for a failed Connection attempt in the logfile, please elaborate on the local time, your try failed.
